Should catsup bottles in restaurants be opened by employees of the restaurant?

Tonight for dinner I went to a well recognized national chain restaurant that specializes in serving hamburgers. I will not mention the name, but will say that this restaurant chain is not a fast food type of hamburger joint; instead, this hamburger joint servesgourmet hamburgers cooked at the time of order. I order my hamburger at the window then I found a table and sat down. Before my food arrived, I decided to prepare the condiments I would need for my dinner. I decided to use catchup on my onion rings. I had picked up the catsup bottle and was surprised to find it to be a new bottle of catsup with the seal still on the top. When I was removing the seal off of the catsup bottle I noticed how my hands touched the top of the catsup bottle to remove this seal. I had to open the bottle, peel the plastic seal off of the top, and replace the top. Fortunately, I had washed my hands before I sat down to eat, but what if I was one of those people who either seem to forget to wash their hands after using the restroom or pick buggars from their nose. Some people do both. I think this is a health hazard because most likely this bottle of catsup will be around for some time and if bacteria is introduced into the catsup it will most likely be able to propagate. I am certain that I will no longer patronize this restaurant. am I being paranoid?
