In my last year of university around 2007ish, I worked as a hostess and waitress at a cool restaurant in the heart of Toronto. It was busy, and the hours were late, and I'm pretty sure the whole place was run by the mafia. I'm deranged enough that I thought I could befriend the (mafia) owner of the restaurant, and also the rage-fueled chef. I can assure you neither of those things happened.
But I did learn how to lie to people about their wait time for their table to be ready, how to climb a ladder in to the basement which was a thing of nightmares, and how to appreciate that the person who is serving you (whether this is their profession or not) is worthy of respect and understanding because at the end of the day, we go to restaurant to enjoy in the ritual of eating delicious food with people we enjoy. And that is a beautiful thing we should remember to appreciate.
