Went for an ice cream yesterday at a local place, in another neighbourhood. After i make my order and they make my ice cream, they tell me they only accept cash and I can go to the ATM right there to take out some cash. WHAT IS THIS!? 1985? ...So yeah, i paid a 2,50$ fee for a 5$ ice cream. urgh. It was good tho, i'll come back with cash next time.
The place where I get my haircut accepts credit cards but they will not accept a tip on credit card. Therefore, I always find myself having to come back later in the day or the next day to give a tip to the person who cuts my hair. Eventually, I got so annoyed by this I stopped going there.
My barber is actually cash only, now that I think about it. It's a sort of independent operation run by a few guys in their twenties, but I'm sure they mostly do it for the nostalgia factor. A comprehensive cut costs 16, which means they pretty much always get a 25 percent tip. Pretty good system they've got. EDIT: and at least twice I've forgotten and had to IOU them.
