That could be. I know restaurants are still required to provide information, but I've never really researched exactly the differences between what they are expected to provide VS prepackaged.
That being said, I've never been told no when asking for more information from a restaurant. Usually whenever I've asked about something they will tell me what's in it, and even let me see the ingredients label on the packaged food they used as ingredients. Not surprisingly, restaurant owners and employees don't want their customers having allergic reactions.
As for the OP: Clearly your customer isn't allergic, nor committed enough to her lifestyle choices to bother looking into this. Obviously from a business perspective if you tell her she won't continue to eat your fries. And while you are legally required to provide some information (possibly not even this information) you are not required to ensure customers know this information.
Ethically speaking, this is a bit more complicated.

Except in cases where the indirect food is one of the 12 common allergens. In which case you see phrases like "Made in a factory that also processes peanuts".
Moreover, frying grease is a direct ingredient. You wouldn't be required to list something like chicken breading in your fries cooked in the same oil, but the the oil itself is a direct ingredient.

@spiderwoman Vendors, atleast in the United states, are required to provide nutritional information to customers. Including ingredients. Granted, you may have to ask, they are required to provide the information. Most restaurants post this online anymore.
McDonalds actually fell under a lot of controversy over this a while ago, because they posted their nutrition information, and then hid it behind other posters.

That sucks. I lived with a woman for a while who had the same thing.
Also, you are legally required to disclose what is in food. However, for the most part a sign that reads something like "this faculty contains allergens and no food can be guaranteed allergen free" will protect a business from lawsuits. Cross contamination is very real and difficult to avoid when you prepare so much food.
Unfortunately people with deathly allergies just need to be really careful and distrustful of eating out most places.

It should probably also be noted that drive them out was mostly slag for force them to convert under penalty of death.

Foster Care isn't actually very profitable anymore. Unfortunately to make any money out of it one has to neglected the child pretty hard. And good parents are actually cost money by having foster kids because the state doesn't give them enough to take care of the child properly.

Maybe then you'll hear the words I've been singing, funny when you're dead how people start listening.

No, it will be better than what you would have gotten. For example, my aunt has a birthday the 26th. And I usually get her something small. But I don't get my other aunts and uncles anything for either their birthdays or Christmas.

It won't affect supplements. But it would affect both prescriptions, and over the counter drugs like Ibuprofen.
That being said, if this is a literal agreement then you find work arounds. If it's more based on the spirit of the thing, then you can probably buy medications, so long as you aren't misusing them.

4.Education Opportunities shouldn't be determined by wealth. I am not saying it's wrong for parents to give their child the best they can afford. What I am saying is that Sally who is brilliant doesn't deserve bad education because her mother isn't successful.
I had a friend who referred to birth circumstances as "the parent lottery". Lucky kids got good parents and especially lucky kids got rich parents. And unlucky kids didn't.
And maybe it's TRUE to say that the children of unsuccessful parents are likely to be unsuccessful themselves, this isn't always the case, and certainly it would be helped by better education for all.
We aren't even arguing that lazy adults should get handouts. That's an oversimplified argument. But it's not the point here. Kids don't deserve to be punished for their parents shortcomings.

The link is worth it. It's also safe for work.:)

Same honestly.
I like tomatoes, and I like BBQ sauce, but ketchup is generally pretty awful.
