"The praise for your catering skills just keeps coming in ...the food was delicious, the place looked great, your staff was professional, nice, and unobtrusive all at the same time....etc, etc. Everyone who pays attention to these things was impressed....enough to say so and ask for your name.
It should go without saying that I/we appreciated your work even more. It is amazing how you can size up a place and in such a short period of time and transform it into a party space using the things that are at hand. My neighbor (the cookie lady) who is not shy about being critical raved about you. She was especially impressed by the food stations and how that prevented the typical crowding around the buffet table when food is served. She said the chocolate cake was the best she had ever had (glad you were able to bring it on short notice). My mother, ever the German housewife, could not get over the fact that the last thing you did before you left was mop the floor."
