Well said. We do the same with our dog. Never off leash in public spaces and also did a lot of on leash crowd training so she stays calm when being randomly approached by people. We run her before going to a pub and have her under a table at a welcoming outdoor terrace. We will leave if any problem, which I think only happened once.

We also have a different problem. Our dog is beautiful so gets approached and petted without us being asked and before we have time to sit her down and get her in a calm state. So we worked on that too, but I wished people just asked before approaching us. Especially sending their kids running towards my dog. She's never reacted badly, and we're in good control, but why send your kid towards an animal you don't know, especially when she has the hunting skills to hurt your kid (small prey) in a flash if she decided to?

Basically no one should impose their dog to someone who doesn't like them.
I am sorry OP feels many owners don't respect their boundaries.

Similarly, no one should impose themselves on a dog and owner either.

Live and let live.
