Why would the man be so rude!? He doesnt know you and you dont know him based on your description "some guy" Yes, Jukka may be a very cute dog but she is still a dog. People like him need to learn to respect animals. The smaller the dog the more disrespectful some humans are. People are always running up to my dog and rubbing her and petting her head and i hate it. I'm constantly telling people they should ask before petting anyones pet.
Poor Jukka. I would have pooped on him too if i were in her situation
Don't go into hiding. The next time you see that man, you let him know that he should ask before touching anyones dog let alone grabbing them away from their owners.
As for the guy you've had your eye on.... dont let it hold you back from possibly saying something. If he brings it up you can always say "accidents happen to the best of us".
