Is it bad etiquette to use a credit or debit card to pay for single figure amounts at the POS
I don't carry cash at all unless I know I'm going somewhere which requires it - this includes going to the corner shop for some milk or going to other countries for a week. Cards are easier for me - if a merchant wants my business they will take my money through whatever means they can. I don't think etiquette comes into it.
