We were walking past a building site earlier and this bloke who was on the scafolding shouted something down to his mate and did this irritating hand action thing. I put my shopping down and shouted back up "willy, willy, willy!" and copied the hand action. The bloke then shouted down to DH that he should keep his dog on a tighter leash (meaning me) so DH shouted back "get lost" so another builder told us to fuck off before DH ended up getting filled in. When we got home I told DH I was reporting the blokes to their company and he said not to as they could end up getting fired and it was all my fault anyway 
I did however report them for threatning DH. Did I do the wrong thing? I know in this current climate losing your job is a terrible thing to happen but they shouldn't have threatened DH. I am feeling a bit guilty though at what might happen, especially if they have families etc
