I'm struggling to see why the manager thought I was unreasonable; this being AIBU someone must have a theory. Anyway I've sent off a complaint as it's a small chain.
The description of what happened is:
"I advised your manager that having 2 racks of high chairs blocking the accessible / baby change toilet door from opening more than 12 inches makes the toilet inaccessible for a wheelchair or a pushchair. As a regular customer, I already said this once since the makeover, because an old man with a stick struggled to get in, but they are still there. He said that is the designated spot for them and they can't go anywhere else, then walked off. A woman with a slim pushchair arrived some time later while I was eating, obviously couldn't get her pushchair in, so she restacked some high chairs and went into the toilet. The manager grabbed the chairs and put them out of the way by a table then ran over to me and very aggressively shouted at me that high chairs mustn't be stacked more than 3 high and I was creating a health and safety issue. I told him I hadn't touched them and it was nothing to do with me but was the woman who was still in the toilet with her pushchair, he said "I thought she was with you" then stamped away. She wasn't, but even if she was I shouldn't be shouted at in front of my toddler because another adult removed an obstacle that was preventing them from using the toilet."
Keeping this short, but I did add on the complaint about not going back and how I think they really need to keep the accessible toilet door actually accessible.
So, any ideas why the manager thought I was being unreasonable? Is it because I complained on two occasions about them blocking the accessible toilet door? I was polite so I'm still a bit shaken and baffled as to what else I should have done.
