pay cash and be looked down upon?

I never know how much to tip, and often forget to. It makes me feel bad when I remember as I'm driving away though. *sigh* It's hard to do that when there is no option to pay for one with debit on your ticket, and you don't have any cash. For that reason, and because sometimes you just want to give somebody a five for whatever reason (pizza pool, sharing gas expenses etc.) I carry a small amount of cash. Everything I can though, I pay for with debit since it's easier to keep track of what I've bought that way.

Anyway ... I havn't noticed anyone being looked down upon for paying with cash before, but then it's not really something you pay attention to eh?

Jam it back in, in the dark.
