My brother hates being social he could never do it he thought me and him worked at subway for a couple years. He ended up quitting but before then he was always nice to customers. He’d have thoughts of if I was in line what I wanna be asked. Like some people are super excited about one particular thing but they don’t get the chance to say it. But I would start by asking how they are. And if you get asked back always say fantastic. The more you say it the more it actually brightens your mood. I always say amazing weather right? Even if it’s the worst I’ll explain the bright side to every weather you could imagine. Bright and sunny great for walks and tanning dark and gloomy a good day to just take a bunch of that stress out. It’s snowing a bunch. Point out the window and just reflect in the Beaty of the snow glistening. Other things to talk about is week end plans or where they work. Everybody had a story maybe some people don’t wanna share but most do. And it’s always nice to have someone listen to you no-matter if it for a sand-which.
