On the inside I would have been screaming, "AAAARRRRGH," while on the outside I would have smiled and said, "Sure."
As in so many other situations....
Reminds me of a typical day on the ER shop floor...
A few days ago I was at school, and I had a disabled student come up to and ask me if I would help him use the restroom. I didn't really know how to answer that, so I acted like didn't understand what he saying.
Others have spoken about your pretending to not understand him, and I agree with them. By all means, refuse to render assistance if you're that way inclined, but there's no need to insult him by acting dishonestly.
I should add that he can't walk, needs help taking off his jacket (I saw him get help removing his jacket earlier that week). But I also didn't want to help someone who I didn't know get on a toilet, and possibly more ( I can't say he would need more help than getting on the toilet). But he did get someone to help him, and that person was gone for a while, at least 6-8 minutes so I'm guessing he did help him onto the toilet, but past that I have no idea.
So, would you of helped him out or not. And do you think I should of helped him?
Obviously he was male, and so am I. And his speech was very hard to understand as well, I did have a hard time understanding what he was asking.
If you found out precisely what was asked of you, you might have acted differently. Suppose he only wanted you to take off and hold onto his jacket or walking aids, or to just lift him off the seat? Did he ask you to wipe his bum for him?
If it didn't inconvenience me and I wasn't doing anything urgent, I'd help out and do what was required of me. In this situation, I wouldn't volunteer any actions that seem intimate or overly personal as it might seem inappropriate - unless I was requested to do so in which case I'd also do my best; or if it was a dire situation in which case I might also call for further assistance.
Who knows, it could even mark the start of a new friendship. Such things occur in the most unlikely of circumstances, or at least that's what television has taught me.
