I could write the same about the cretins in hotel lounges who ignore the tongs or other implements, pick up food in their bare hands, and sometimes even pop it into their mouths.

I observed that most recently in a Hilton Lounge in Germany. The older woman doing it happened to be French - her companion muttered something to her when she caught me glaring at her - but ignorance transcends nationalities and I've seen this disgusting behavior carried out by a variety of customers way too many times in lounges for me to think it's a rare occurrence.

I've also seen it at restaurant buffets and it offends me just as much.
