.....sorry, this is a further thread jack...and liable to be missed by folks who should see it....but, sigh..i need to say.....
....adding a little bit to my "regular" and playing the "game" comments above. it happened to be convenient so i picked up and delivered my own O2 tanks...they loved it, saving them money and hassles.... AND, for me, keeping a face to the "file". also, lugging your own tank(s) with their frigging name on it makes it REALY hard to deny that they "carry tanks". the downside here is that developing a relationship with the delivery drivers can be immensely beneficial. those folks see and hear and "get" the patients at the other end of these tanks. there is many a clusterhead who can attest to delivery drivers going far above and beyond for them. also, never hurts to poke your head into the back room and introduce yourself to the techs who fill tanks and prep equipment..a thank you goes a long ways with folks who rarely see YOU.....
