Well, some jobs do require employees to work holidays. I worked 42 consecutive Thanksgivings until I retired. And I was thankful for the restaurants that were open on Thanksgiving as my employers always had a catered Thanksgiving meal brought in for those who were working.
But I have to admit, I had no idea Olive Garden had been open on Thanksgiving. But I know folks who work in the restaurant industry and Thanksgiving is one of their biggest days.
Anyone remember Christmas 1988 when Dennys decided to close and give their employees Christmas off, only to discover many of their restaurants didn't even had locks on their doors since they were normally open 24 hours a day, 7 days a week, 365 days a year.
