American here, 99% of the time I use credit cards. It's just generally easier than carrying cash and nearly all vendors accept it. Beyond that I get a % back as points to trade for gift cards or in my case plane tickets. Another item is that if I get robbed I can quickly recover or head off any lost money.
Yeah I get that just in the UK they're much more commonly used than credit cards. The way the post I replied to was worded sounded like it was cash or credit and that's it
We do, I have a couple. I don't really use them though, you don't get the points. I always make sure to pay my credit cards off each month so it's worth the points for me.
