What could you do with a Lint Roller, a Rubber Ducky, and Wolfie?
Do the logical thing. Tell the mechanic to sit in the car or drive it over speed bumps himself. Sometimes I think they just want to be deaf Ride with them and point out the noise. Either they can tell you what it is or in most cases (it won't happen when you take it to the shop).
Were they sugar free? If so, read the label and see if one of the ingredients is SORBITOL. Sorbitol is an artificial sweetener and it can cause diarrhea, especially if you eat a lot of it.
