I would consider this if his written comms were good.
I've had a few problems with deaf clients, one of whom I did meet but found on subsequent appointments it was taking 30-40 minutes of back and forth constant texting to set up, which was very difficult considering he was asking me to see him at short notice, and I was trying to get back home so I could get ready. All I needed was to know when and how long for, but somehow he managed to string it out.
Other enquiries claiming to be deaf have starting going off into realms of 'can you describe this, will you do this service which you don't offer..........' fantasy, sexting land.
So succinct good comms, yes I can do it. Taking the P, no I do not. This goes for able bodied, deaf, disabled, whomever.
Taking the P, no I cannot.
