I didn't have a problem with anyone, the only problem I do have that stops me attending is arthritis of the spine. if I sit with no neck support for any length of time I'm in pain for the next couple of days.

I'm sure no one would mind you coming with your collar on if that's what you need Alsatian ( no pun intended ) Pain isn't funny!
I can be quite 'selective' who I mix with but found everyone very friendly with no bitching.
All makes for a good atmosphere and the proof was in the pudding as the saying goes as we went again the following year.
