I always think they don’t want me to go near their dog so stay away or walk further away from them.
When I was walking my dog today I put her on the lead because she can sometimes be reactive to other dogs. Mostly she’s fine but she was attacked and gets scared if dogs approach her sometimes and I could tell she was in one of those moods today so I put her on the lead as the other dog was approaching and started walking a bit away from them. The man kept coming directly towards me, he had a big husky so thought I was putting her on because I was worried his dog would be aggressive. He kept walking towards me saying it’s ok he’ll only want to play, I was like I know but my dog won’t want to 
Am I unreasonable in thinking if you see someone recall their dog and put them on a lead you stay away? Not sure what else I could have done to keep her away? She started showing her teeth, she doesn’t go for the dogs just warns them away because of her fear, but I always worry about the other dog reacting to her and things escalating.
We have been going to training classes and she is getting better but doesn’t like dogs who jump around her still. Walking past dogs etc she’s absolutely fine.
