I have had this type of thing happen a number of times. The worst was when I had a wheelchair bound client visit me, which took weeks to prepare due to various accessibility issues of work premises. We discussed the booking in full. He wanted strap on, assured me that he could move certain aspects by himself etc. When he finally arrived, it was evident that he could not move at all. He told me I had to lift and drag him about. And here's the kicker.... He then told me it is likely that he will shit himself. Especially during strap on.
I am a very empathetic person but NO WAY was I dealing with that, especially when he had ample opportunity to tell me these things and purposefully waited until he arrived.
I think a lot of men withhold information because they know we'd refuse to see them otherwise. Very disrespectful.
