Ive noticed that places such as Denny’s, used to have bottles.of ketchup and salt and pepper shakers on the tables. They took those away as a response to the pandemic. The story about ketchup here should also apply to salt and pepper and mustard.
I think they removed them from the tables, so as not to have to sanitize them so frequently. If you had to ask for Ketchup and/or salt & pepper, they would bring it.
