A fella I know,through a mutual friend,was coming out from Galway shopping centre many many year's ago with another couple mate's of his. They walked towards their car to find somebody trying to brake in. Rather than freak out,they asked the man in question what was the problem and could they help him. He said he locked his key's in the car and was trying to get them. When the pri*k was asked,"these key's your looking for"he tried leg it. The fellas in question were not the kind of people you would be brave around let's just say. They opened the door car,put his hand in between door and car and gave it a few good thumps. I always thought this was a very good way to teach people not to interfere/steal/or damage another person's pride and joy
