The FA was uncouth and unpolished.

And she was insensitive with respect to thinking that removing the ham (however she did it) solved the problem.

But, in this instance, she did not touch food that was to be consumed. But it leaves me to wonder what else she might do one day . . . .

At bottom, however, if one finds something like this intolerably nasty, one should never eat food that one has not prepared by one's self. I assure you, we have all survived far more unhygenic practices, likely without knowing they occurred.
