Soon there will be a black market for bagged lunches in “hi-tech” areas of SF.
I’ve worked in a lot of office buildings, some with cafeterias, some with deli’s in the lobby. Everybody doesn’t eat there. In fact, most don’t. The only place where it was REALLY busy was a place where you had to get in your car and drive a few miles to find a place to eat.
But I’m old. I bring my own lunch and have for many years. I’ll eat out once every few weeks.
However, those restaurants who build up a ‘DELIVERY’ service might like this. You are still eating in your office, but there is no Industrial Kitchen.
