In our house, "No Tzatziki Sauce" has become synonymous with anything I don't like. My list of foods I will not eat is very long and when we go to a restaurant there are always things I do not want on my plate. If I don't like something, I don't want to look at it, have it near my food and for goodness sake I don't want to smell it or have it touch anything! Mayonnaise, ranch dressing, guacamole, mushrooms, sour cream, and pickled ginger are all offenders.
And when we go to Daphne's it's "No Tzatziki Sauce!" I know they put it in a little cup but sometimes it spills over onto the plate and then I make the face. You know the face--the one that says "Ewww! This tzatziki sauce touching my food may kill me!" I have been known to order "No Tzatziki Sauce" and then order extra on the side for someone else just to ensure my food doesn't get contaminated (I'd rather pay extra then have to eat "tainted" food)
Sometimes, Matt likes to go through the Starbuck's drive thru by our house to get himself a cup of coffee. Imagine their confusion when he orders it with "No Tzatziki Sauce!" just to make me smile.
