Funny how many folks who ride will enter an establishment 'incognito' when they aren't riding.
I know of a bar whose owner made the mistake of telling a couple of fellow riders (dressed for the road) they didn't want bikers in their bar.
When they graciously left, so did over half of the people in the bar, who just happened to not be in leathers that day. Within 24 hours, the word was out, and the business didn't make it a year.
Any restaurant which would kick me out for being 'homophobic' doesn't need my business, and other people should be advised of the fact (and the reason) to spare themselves the embarassment and/or inconvenience of being refused service.
It is amazing how quickly 'the word' about a discriminatory business can spread, isn't it?
Fortunately, in recent years, with motorcycles enjoying a previously unseen level of popularity, discrimination against "bikers" or those in "biker attire" has been reduced to near-non-existent in my neck of the woods.
