We had the same thing at a cafe for lunch a couple of weeks back. Slow service, the manager apologised and said they've only just gone back to capacity, lost most of their staff during COVID and now struggling to get (suitably experienced) staff. I'm sure it's a real issue in some hospo.
I went to a Glenelg dinner at the Grand
Bar staff didn’t know how to pour a beer. Clearly had never done it before. Not entirely sure why they couldn’t have got them in 30 mins earlier to show them
Waiting staff didn’t clear the dinner plates from the table before dessert came out. Not enough to do it all. We ended up doing it ourselves
