Sign at a coffee shop

A small amount of politeness goes a long way.

"Hello, can I please get a small coffee? Thankyou!" Can I pay only a dollar for that

*Grumpy Cat* "Here's $5 just give me the damn coffee."

"Hello, how is your day going sir/madam? I'd like one small coffee, please." $0.10

Good day to you sir! might i complement your hair? ah yes, i would like a small coffee, if it wouldnt be too much trouble
