I use card for near everything. I do carry cash just in case...like for tips or certain businesses that only take cash. I always get paranoid I'm gonna drop and lose the cash though lol
Card, or really my phone because it's a lot faster to process and more convenient.
This is to the point where any cash I get (mostly from my grandma lol) just accumulates in my wallet forever until I eventually realise I carry way too much of it. I do like to keep some cash as a backup though, so that if my cards ever fail or if electronic payments are down at a store I'll still be able to pay...
