"I know I am disabled and that somwtimes makes others uncomfotable"
If they are then as humans they are very shallow and to be honest you would not want to dine with them anyway
In my social acceptable mind and as a non disabled person with a social attitude to life I find it really hard to understand why having a disabled person at their dining table would make others feel uncomfortable.
There is no true answer to the problem you present, you can only hope in life you find more folks that are accepting of others than those you may meet that dont and if they dont shame on them and ask to be moved,,,,,but dont go into hiding in a table for one or two or the buffet.
Disabled or not we are what we are,,,,diverse
