Do you check everyone's card when you split the bill? What makes you think the others are debit rather than credit cards?

For info: the debit & credit cards from my bank look almost identical. The only difference is one says "credit" in small black text. My credit card handles exactly like my debit card in terms of tap-and-pay etc. I just wouldn't use it to take out cash from an ATM, but then I can't remember when I last needed to do that.
