Pizza delivery girl blatantly asking for tips, what would you do?

This is a dominos in BR FWIW. She tells me she depends on tips for a living and would really appreciate one. I was thrown off a little. I Dont live in a low income area or anything. So I just said something like yeah that's pretty normal right, I always tip. So I actually tipped less than I usually would have bc for whatever reason it pissed me off that she thought she needed to instruct me on something that I consider expected anyway. Almost like an insult I guess bc she apparently thought I was a bad tipper. So I handed it back to her with $2.00 written on the tip line. She then looks at it and asks me if I could tip $5 instead bc she needed to save money for moving. I just said no I'm good with $2 and she kind of awkwardly walked away. I order Papa Johns pretty much exclusively for delivery but decided to try Domios to mix it up. Out on them now bc I'm pretty sure I have a note on my customer file to spit in my next pizza. Not to mention I cant risk having same woman deliver my pizza bc it might be worse than spit after she gets the pizza out of the store.
