Most of the hotels I go to are “cash free”. It doesn’t bother me in a practical sense. It irritates me when I see the signs.
Nothing wrong with allowing people to use cash when they want.
(Although i tried to take $30k in cash to buy a truck once. The dealership wanted no part of it. And that was in 2012.)
I once bought a trailer for $28,000 in cash in 2019.
We stood at the window of the seller’s bank while their machines counted out the deposit.
Everyone was happy that there was no chance of fraud.
