After years of working with the public (retail, restaurant, and call center) I understand that the public is annoying at times. I hated it when people would just ignore me when I tried to be friendly to them while I was ringing them up or waiting on them. A lot of people would act like I didn't exist. Like the products just magically appeared in a bag. Others would be too busy talking on their phones to even acknowledge me.
So I make it a point to always say "hi", "please", "thank you", and "have a nice day" to anyone who is ringing me up at the grocery store or waiting on me at a restaurant. I know how it feels to be treated like crap, and I don't ever want to do that to someone else.
So it really makes me angry when people who are waiting on me act like I don't exist. I went through the drive thru Friday at lunch. I asked for mustard and jalapenos only on my burger. When I got to the window the lady didn't even say "hi". She just repeated my order. It sounded right, but I had a feeling it was going to be wrong. I asked for 2 packets of ketchup when I paid and she didn't say anything. When she thrust the bag at me I said "thank you" and she just shut the window in my face.
Of course when I got back to work I had lettuce and tomato on my burger and only 1 packet of ketchup. I was pissed! I know that I should have checked my bag before I drove off, but I didn't want to hold up the line. And who knows how she would have treated me if I told her my order was wrong.
