Needed a wheelchair this morning at 7:30 a.m. when we arrived at Reynolds Tower for P.E.T. scan appointment. Asked security sitting at a desk for a wheelchair for my 88 year old father in law. He stated I would need to go to Ardmore Tower and ask for wheelchair. WHAT???!!
I'm 62 years old and not in the best of shape, but I secured a wheelchair and ended up being tardy for appointment. What happened to service???
