I experienced similar in 2004 as well. I was also pregnant and also a man with a kid on a stroller also did the same to me ar !!! BB展係多人, 但係都唔駛用BB車撞人腳跟lor. It hurts ga mar !!! I found that many people (in particular mainlanders...........as some said腳不踏上心不'踏實' ma) like to follow tight the people ahead ga..............大熱天時咪搵D咁野玩 ma !!!!
