Hello, I'm Laura. I'm probably not a terminator. (b'-')b
You have one cashier/waiter/barista to make that dumb joke to. They have hundreds of you telling them that dumb joke all day.
When I grab something for you behind the bar, do not tell me “Oh, I didn’t know it was just there, sorry!” STOP. DO NOT REACH OVER THE GLASS. DO NOT TOUCH THE BARISTA’S TOOLS. DO NOT TOUCH THE BARISTA’S SUPPLIES. DO NOT PUT YOUR HANDS IN THE BARISTA AREA.
