I know another one, and yes this is quite trivial really.
Last week we went to a gorgeous new cafe, sat down, and within a minute I realised a large dog had appeared and was licking dds outstretched hand (she was delighted of course) then we had to get up and go and wash before eating, only to see the dog licking her hands again. Argh. Then it turned around and was wagging it's tail into me (I'm unfortunately allergic to fur and would rather not have to have fur on my clothes) - we werent even that close to the other table. It's just so annoying and I know I can ask it's owners to keep it away from us but seems a bit cruel to the dog and I jolly well shouldn't have to, they should be keeping an eye themselves without me having to have an awkward chat. Manners are meant to make everyone feel comfortable and not force people into seeming unreasonable because they don't want to get involved with the animal.
Then this afternoon, different cafe, on my own this time and got the fright of my life when all of a sudden a dog snarled and snapped at a child a few tables away, who of course screamed and was very distressed, someone could have had a heart attack!
I am going to have to be more mindful of places which don't have dogs in future I think.
And I imagine I am probably going to be told I am being unreasonable. I just want a coffee in peace without slobbering or snarling dogs
