Sorry for your bad day Jamie. My daughter's first job was retail, so I did learn to appreciate it a lot more from that direction.
I think that I am nice to all retail, waitstaff, etc. They are usually the ones that make whatever "outing" more fun for me!!
We must be pretty friendly because we usually end up chatting up a storm with all the help.
Hope tomorrow's better for you. Someone will come along and make your day!!
