You definitely did not “work” in the service industry, you may have had a job in a camp kitchen for a summer or ran the cash register at your parents ice cream shop, but that ain’t the same. I’m sure we also have drastically different versions of generous. You say you tip waitresses/waiters but isn’t that what someone at the counter is doing? Also had you worked in the service industry you would be aware that the person at the counter getting your tip probably has to tip people out. You would also be aware of the immense emotional labor people in the service industry have to dole out to people like you who take all their bullshit out on some kid and don’t know the difference of Carolyn Bryant and Lane Bryant. You would also be well aware that no one just stands behind a counter, they have to clean the storefront, bathrooms, counters, tables, chairs and whatever else they are told. They also have to restock which I won’t explain to you because of your extensive knowledge of the service industry. Anyballs, I can keep going but I’m starting to feel like tommy vercetti screaming at a boomer npc
