It might be, but, having owned a restaurant (not in SF), it doesn't ring untrue; some people are complete dicks all the time anyway and think because they are on the paying side of the table they can get away with anything and, as far as I have seen (and talked to the new owners of my ex restaurant) in the past weeks when travelling for the first time in 1.5 years, their fuse became just a bit shorter. When before they wouldn't have been nice (let's say they were difficult) while waiters would bend over backwards to accommodate them and then get a 2* star review (with made up things often!) anyway, now they become visibly agitated up to downright violent. It is probably temporary (hopefully?), but it doesn't ring untrue to me.
