One of the most ridiculous tipping related thing happened a couple of weeks ago. I was ordering some pantry items from an online store that shipped to me (shipping fee was separate, based on how much is purchased). They had a vinegar that I couldn’t find locally or online elsewhere, and since they are a small business, I decided to order a few other things to support them even though all their prices were a bit higher than other places. When checking out, they asked for a 20-25% tip to help support their small business. That just made me mad. Never going to shop from them again.
