That's happening everywhere. Every restaurant I've gone to since the pandemic began and then ended is having this problem. Same for every retail establishment, grocery store and more.
Last night GF and I went to a favorite restaurant we hadn't been to in over a year. 30 minute wait for a table in a VERY large establishment where about 25% of the tables were occupied. They didn't have enough waitresses, cooks, staff to clear and clean tables or enough bartenders to meet the 25% capacity they had.
I thought under the conditions our waitress did very well and received a very nice tip. (That's my practice.)
turned out it was because they were short of staff also.
