I remember a woman ordered her coffee with cream so I made it with half & half and she got mad because she's "on the keto diet and can't drink milk"... I couldn't help but say cream is basically milk but I remade it with heavy cream as she struggled to angrily explain what the difference is.

Meh a keto customer orders and iced coffee with sfv and sfcd with hc and the next customer orders a wcm with 10 pumps cl, so it's not like keto is harder or anything. I'm not sure why keto people are annoying to baristas.
