I feel you.. Some customers just hate being wrong and feel entitled for us to read their minds or something. I recommend asking them a million questions while they're still at the box. For example when they ask for an iced coffee ask them if they want cream, this question tells them iced coffee doesn't come made with milk. So then they'll probably question like "doesn't it come with milk already?" And you can tell them right then and there, it's a latte they want. Because they can say one thing and mean a completely different drink. So take your time while taking their order at the box, make sure everything is how they want it before they come to the window. That way your drive time won't be affected by these types of mistakes. I know it's irritating and annoying but you got this!!

Customer: “I want the salami egg bites.”
Me: “ok like the bacon egg bites?”
Costumer: “NO I said salami egg bites”
Me: “I’m sorry we don’t have that.”
Costumer: “ok so you’re out and you aren’t even going to check?”
Me: “no it’s not on the menu, ma’am.”
Costumer: “you must be new here or something. Can I talk to someone who knows what they’re doing?”
Me: “I’ve been with this store since we opened in 2017 and we have never served that item. Would you like to order something else?”
Costumer: *drives away*

This happens so often. Except they say they want an iced coffee with caramel, so I give them caramel syrup. "No, this is supposed to have milk" man just tell me you want milk.

You can add a splash of milk to iced coffee, though, so they didn't necessarily want a latte. However, most people who have ever ordered a cup of coffee anywhere on the planet-- Starbucks, other shops, diner, McDonald's, wherever-- know that you should specify if you want cream or sugar. You not saying "with milk" or "with a splash of cream" is not something to berate a barista about.

Caramel caramel caramel lol

Carmel is a city in Jersey I think.
