I studiously avoid shopping during Thanksgiving, period. Some people like the crowds and the noise, and the challenge, but I want to shop by myself, without standing in long lines, waiting for my turn at the check-out where the clerk may or may not have been having a good day.
My favorite time to shop is 5:30 AM. :o])
Most of them aren’t having a good day because people can be such jerks. I try to be nice to retail workers even more at this time of year.
