And in the exact wording used at one of my last interviews by the hiring manager, “We can’t hire you because of the dog...”. Yes, said out loud not once, but twice!! LOL
Discrimination much, but was stupid enough not to even attempt to hide it.

I filed a charge with the EEOC.

what was your response?

To my knowledge an employer may deny you employment based on a service dog if it would be an encumbrance to the business, or ask you to not bring them to work. A good example would be food service, as it may conflict with health codes. If you can see no reasoning such as this, I think it's good that you have stood up for your rights and reported it.

I've never met anyone like that, however:

I went to a restaurant with friends and asked for a Braille menu because I was fairly certain they had one. The waitress gave me a blank look so confused even totally blind me could see it and said "Braille, Braille? Is that the one with all the healthy food alternatives on it?"

"No, that's the one with all the little dots." my friends could not stop laughing at this response.

hi all, thankfully, I turned up at the interview and there was no problems. It's a ital digital marketing sales role.

Pretty sure that she knows what a guide dog is. In her mind perhaps this odd behaviour is to discourage you from attending because she doesn’t want a blind person.
