Please remember to be kind to the people you encounter that work in the store you're shopping in.
Chances are, they had to get up earlier than you this morning to prep the store for your arrival, and they're the ones that have to stay afterwards to clean up after the onslaught of people.
Chances are, they're missing out on their own holiday shopping to be at the store so you can get yours done.
Chances are, if you're that one bad transaction for the employee, you're going to ruin their whole day, and be the type of person that they associate Black Friday with as an example for their reason for disliking it. DON'T BE THAT PERSON!!
Just a little PSA from me to you. Thanks and have a great shopping day.
