Ann, you might throw in some hard candy and some cracker snacks.. nabs or those Handisnacks that have cheese a little knife and cheese spread ( if you have seen them, you would know). Your idea is very good and original.
Other things that were done at our Cancer center were a cart with ice , cups and softdrinks was rolled around and they approached the patients and whoever accompanied them and offered them drinks while they waited for doctor appointments or were getting chemo. Another thing they did was bring in a cart loaded with cake, cookies, finger sandwiches etc. and small plates and napkins.
No wonder I'm so fat, all I think about is food..
