Some people just take their job too seriously

Maybe because, it's policy?

It's policy and they watch the cameras religiously. If you sell alcohol and not check ID you could get fired

Take their job too seriously? If you are getting paid to do something you do it. If you can't handle a small task, no one is going to give you more responsibility.

Just buy a gift card that way you don't have to pay for a membership and pay with a normal credit/debit card

Do your job right. Don't half ass it.
