I just returned from a resort - all-inclusive. The amount of people I saw going up and just PILING their dinner plates and only took a taste or two of stuff and went up to get the stuff they liked, leaving the rest to be tossed, still amazes me (a country where food in quantities like that are incredible to the staff that work there and as they have told me that this offends them to have it thrown away (they are not allowed to take it if it is left on the plates - but trust me, if they could, they would!).
I, myself, took the salad plate, took a very tiny portion of what appealed to me, ate those and went back for more of what I really liked.
What really disturbed me, however, were the grill station vultures. You can choose between various raw fish/chicken/beef/seafood varieties and have it grilled to your preference. The flat grills are quite large. The number of people who would stand in front of the station and "guard" their cooking food was nuts! Dagnabit - the chef could have been cooking 15 peoples selections without a problem (there was a different grill station for those with allergies), but NO - they had to watch their individual meal cooked and would quarterback block anyone who wanted to give in their order.
I would just gave my order to the chef, walked to the other stations and selected my sides and came back when it would be done.
Don't even get me talking about the "lady" who refused to share the bread toaster (one of those revolving belt ones) with anyone else (she also did not use the tongs when choosing her bread and had to take not the first or second slice of the pre-sliced, but feel through until the slice felt perfect!
When I made my toast - I knew I had time during the rotation to get a fresh juice - bring to the table - get my selection of egg - bring to the table and pick up my toast (coming back to flip to brown the other side - using tongs) - no one was inconvenienced.
Then again - as a lover of e-hell - I know my etiquette!
