Same here Alexa- I can imagine the day when we will be too old for the responsibility of having a dog- and when I would be so happy and grateful to see dogs when I go out and be allowed to stroke them. Emma is a brilliant dog with the elderly- when we host the village 'oldies' luncheon 1x a month- Emma always comes after the meal to say hello to everyone, and for some of the residents of the OAP home- it is the one thing they really really look forward to.
Went for lunch in a local French restaurant yesteray- packed out, so we asked if Emma was allowed. Of course, was the answer- she lay down in her bed and didn't budge or the whole time. when an older gentleman came to sit at the next door, she raised her head and I asked him if he minded her or I would put her in the car. Not at all he said, and asked if he could come and say hello, and she was delighted, and so was he- where on earth is the problem? As said, if he had said 'sorry I don't like dogs- we would have offered to put her the other side or put her in the car.
Again, bad dog owners give us all a bad name. I would never let a dog of mine go to people unless they had made it clear they didn't mind, let alone let her jump up, etc.
