I was tired of getting mixed signals from the guy who was eyeing me at the office, so I finally went over to him and and we began hopping counters. It was really intense.
Counter Hopping
When a customer joins in on a conversation that two employees are having. This does not generally mean that the employees are not working while having the conversation, they could be readily serving the customer while chatting about whatever subject, and the customer rudely jumps in, presuming that the purchase makes them friends.
I was making a latte for this guy and talking to Jen about my boyfriend while she was wiping down the refridgeratior, and the guy was counter hopping and told me to break up with my guy. Whatever, Asshole.
