That is so true!!
OMG - that is just so funny!
DH & I were at WDW last week. He has a prosthetic (his "learning leg" and should be getting his "permanent" leg in the next few weeks). He was also using an
ECV while at Disney. His current prosthetic is loose (stump is shrinking) and it sometimes slips, so it's easier to use an EVC to get around. Anyway, one day while we were at MK, DH needed the restroom and the companion bathroom was being occupied so he rode into the men's room and got his crutches and waited for the handicapped stall. DH told me a guy came out and stood in front of the stall and looked DH up and down and said "oh did you want to use this stall?" (pointing to the HC stall). DH said "no I'm just waiting here for my leg to grow back. What do you think?" The guy chuckled (but didn't move) and continued to look at DH up and down. DH finally said "are you done?" and the guy said "oh you are waiting for this stall. (laughed and then said) oh sorry." and finally moved out of the way.

I told DH the guy was probably waiting to see if the leg was going to grow back.
Another time we were at DTD - it had been really raining that day so the floor in the men's room was very slippery. DH rode into the men's room, got his crutches and tried to stand. Thank God he didn't fall but he almost did. I was standing at the door and heard the commotion. I yelled at him "you ok" he said "no" and told me to come help him (there was no one in the bathroom). So into the men's room I go (almost slipping myself) to help him. Helped him into the stall and told him to call me if he needed help getting out. I start out towards the door and in comes a father and teenage boy they look at me strange I apologize for being there and explain why I was there. They come out and shortly after that DH calls me to help him (the crutches kept slipping away on the floor and he couldn't make it out of the stall to get to the EVC). So as I'm helping him make it back to the EVC...another couple of guys come in - they look at me and just went along and did their thing. I got DH to the EVC and got my butt out of there (all the while averting my eyes and apologizing).

At least they were cool about it and didn't complain or make a big deal about it. After that we (make that me) learned to really look for the companion rooms!
