Yes, it is possible. I don't expect that this represents that grand a percentage of the missing worker pool. Pre-COVID, teens had already been shunning this sort of work, especially in fast food, and seniors have been replacing this (which is a sad commentary, probably well-suited for a /PR discussion). Meanwhile, for several years, I've been saying that the restaurant model as we know it (at least in the SF Bay Area) is not an economically viable model in the long term. The past 15 months have only served to concentrate the days of reckoning.
