I try to mix something or customer and they just looked at me with a weird glare.
Did they say anything to you?
Yes, they just looked at my when I gave them the plate.
It is weird that they didn't even thank you and just looked at you. Maybe next time don't help them.
I think that's the route I'm going to take.
I understand you wanting to do that. It could be annoying having to deal with disrespectful customers.
