I walked in at around 12:00 pm on a Friday. There were three employees behind the counter, including the cashier who was ringing up an order. Other than the person paying, there was no one in line.
The remaining two employees were a woman mixing potatoes with seasoning and a man speaking with her.
Upon entering and lining up, I was not greeted. The potato mixer looked up, saw me and looked back down. The man speaking to her (about potatoes, perhaps) looked in my general direction and turned back toward her. They continued their conversation, without acknowledging me.
This continued for roughly two minutes. At this point, I said (out loud) "OK" and proceeded to walk away. No one made any attempt to turn me back.
I have worked with the public and understand that prep work is an essential part of running a restaurant. However, prioritizing it over a waiting customer, without so much as a greeting, is a surefire way to lose customers.
I'll never trouble them again.
