Thanks for clearing some of those points up. :-)
Are we, as the people paying for the caterer to come and put on a meal for us, really supposed to know to stand over the food and portion it out? How would we know how much to portion?
In my opinion Sisko, that would be like putting your car in to the autoshop, and having a problem after-would anyone expect you to have been standing there turning a wrench? IMO people hire caterers to do the work of preparing, and serving, a meal. That includes portion control, et al.
And while I think you have indeed learned some consumer lessons here, it's still my personal opinion that, regardless of lack of contract etc, well, you trusted this person and she let you down. The buck stops with the caterer IMO period. In her shoes I would feel horrible about letting down a paying party like this. But I rather doubt any caterer in here would have gotten into that position--it's mostly common sense.
Portions, as I said above, I consider 10 to 12 oz bonless a serving, but I always allowed for smaller meat eaters, it pleases them and helps my serve as well.
