Old man....

Last month I went to a remittance center. I will send a money, during processing inside and waiting for long queue I felt this old man stand very close at my back. after few minutes I turned back to him and he is winking at me
I did not pay attention
After few minutes again, he started a move he is trying to stick his bulging frontal in my butt I moved forward but he's doing the same. I turned back and look him mad and very baddddddd!!!!! then he left th line

IT HAPPENED AGAIN!!!!!!

Last night I accompanied my friend to send money, look whos there the OLD MAN is back
He joined the disorderly queue, he did not see yet but I am monitoring his move, I see to it that he's looking again for another victim maybe he go with fun
After a while somebody is touching my butt
Ow comm'on the old man again, I did not controlled my I pushed him a bit and ready to fist his old face
But other people pacified me and they let him away from me. He left immediately. My friend shocked and asked, "what happened?", I said will tell you after this!

Is that old man is GAY or he is just looking for fun/trip?
