Replying to Who else never carries cash?

I use my debit card where ever i go. Sometimes I'll use my debit card to pay for something that is like $2.35 and the cashier will give me a dirty look. Like what's the big deal with using a debit card to pay for something that is only like a dollar or so? The main reason why I like using my debit card everywhere is so that I don't have a bunch of change to carry later on. Cause when you get like 18 cents back, who wants to carry that around? When I use my debit card, all that change eventually ads up. In my opinion, fuck cash just use a card
