When in Dubai, a young girl in abaya rang my doorbell and asked for money. I gave her some but she was arguing it was not enough and immediately a young boy popped up from behind my door. He kept his foot and blocked the door so that I don't close it, while laughing all the time.It was than that I noticed other girls with him at other door of the floor who were conversing with him and laughing as well. I was very young at that time and felt intimidated.
Nonetheless that episode did not discourage me and I continued giving alms, until something similar happened. This time I managed to close the door but within seconds I could hear the group banging on my door loudly and they kept pressing the door bell continuosly.
