I had noticed several times especially on sundays & public holidays that some "Foreign" passengers(Bangladeshi mostly)are boarding from the rear door to skip fares or rather to search for a quick seats.This happens usually if i'm on bus svs 23,66 & 67.The worst incident happens on svs 67 bendy bus where i noticed that 3 to 5 peoples squeezed in before passengers could alight.I recall one incident that i prevent 2 bangladeshis guys try to enter from the rear door and shouted "Come on man,I believe everybody in this bus are paying their fares and board from the front door,And you peoples choose to enter from the rear door,Don't you know that you are actually doing illegal things"?After that they just walk off and wait for another buses and one of them stared hard at me as i owned them some money.To make matter even worse,Some of them even squeezed besides you as they want you to feel irritated and got off so that they can take over your seats and some of them treated the bus like their own by talking,singing or teasing some young women loudly!From what i'm telling,I do not wish to say that all of them had a bad attitudes,But to some only.Second incident is on svs 23,My wife and my daughter seat together with me on the last row of the upper deck.Then again,3 bangladeshis guys board from little india and went to last row near to where we seated and start to tease my wife by staring and blinking one eye to my wife as i do not exists there,All of sudden,I suddenly shouted some vulgar languages at them and one of them apologised to me saying that his friend are drunk.This experiences thought me how to avoid taking buses ply to serangoon rd especially on sundays and public holidays except if i'm alone or with a guy.

,Anyone experience this before?
