I can't help I'm afraid but I've just returned from 5 days caravanning in the New Forest.
How I thought of you when we ate at the local Harvester ....
Having seen the hygiene standards at the salad bar even I didn't eat from it. DS3 has been ill with diarrhea ever since. I'm 99% sure its NOT as a result of the salad bar and fortunately I served him from it but he could just as easily have served himself, touched a bit of salad, and passed his infection on to a significant number of people.
DH saw a person in chefs clothing wipe down some counter tops and then use the same cloth to wipe out some bowls and put them out for service from the salad bar.
If I wasn't going into litigation with my insurance company I would be writing a letter ...
