You know regardless of nworking together this type of response seems to happen a lot with over weight people. I work in a resteraunt , where I bring my own lunch, I have had customers come over to the break area and tell me I should be eating a salad, meanwhile I am sitting there eating a piece of grilled chicken.
The most embarrasing is when you are ordering a meal and the waitress gives you a look like why are you ordering this.....
If it was me and this situation happened again I would just say I am an adult and I am concious of what I am doing. I do appreciate your concern but I have it under control. If this doesn't work, simply tell her , that her behavior makes you feel ridiculed and embarrased.
Hopefully she will get the hint.
Good luck:thumbup:
