Oh NO! If you just had them on one pile perhaps one of the Staff just took the whole pile to look up Tudiabetes to see if it is a responsible site.
I did my Hospital twice, 40 cards that I printed before and then again 3 months later. I put some in the waiting room, some in the flyer area on the wall, some in the examining room that I was in and some in the info basket at the end of the Reception desk. Then I took some to the Library and Shopping Mall, etc. and spread them around.
I wouldn't even think that they would toss them. Think postitive.
