This is mostly my reason too. Using payments networks makes you beholden to somebody else and reliant on their systems working properly. But nobody selling you stuff gives a shit about that, if it doesn't work, it's your fault. So it's better to take responsibility and keep cash and not be stuck because of other people's problems.
Concretely, I went across town last year with my wife to try a popular counter-service restaurant. Their payment system wasn't working, and during the time I paid for and waited for my order, they turned away about 10 other people who didn't have cash to pay.
