Before the pandemic, there were a lot of retirement-aged people working in food service, like an uncomfortable amount. I certainly haven't been out to eat as much as I have before COVID, but what I noticed was a suspicious lack of those older workers I've come to expect working in food service. A lot of restaurants and fast food places are running on skeleton crews, now, some of them with one or two 16 year olds running the whole businesses alone even during dinner rushes.
Most of the people who I knew that died from Covid were not old people. I literally did not know of any old people that died from it. Even my 99 year old grandmother got it and beat it (this was pre-vaccine). She said that she beat the Spanish flu in the 1920s so she would beat Covid in the 2020s, and she did.
