Ungracious Singaporean

Last week as i was on my way to visit one of the corporate account, these was this very drama happen on board the bus..
Coming near to a bus stop, this young lady sitting near the entrance press the bell, whole seated.. and when the bus arrive at the bus stop, she just simply tap her ezlink card but did not alight. Happen that one old lady who was on board the bus saw what this young lady did and start to question her... "Why did you tap your ezlink card but did not alight?".. That lady ignore her and stand up.. That old lady took the seat and keep scolding "You are not honest, how can you tap your ezlink card but refuse to get off the bus", then this young lady shoot back "Old lady, i did not cheat, please mind your own business"..

Then feeling uneasy, this young lady went forward to the driver to complaint about that old lady.. Then this old lady came forward too and both ladies had an argument.. I heard this old lady was say "I was hoping that you will alight so that i can have your seat.." Then come to the next bus stop, this young lady alight and shouted at the old lady "You are an busybody old lady, very irritating.."

There is nothing the driver can do.. Everyone on board are shaking their head in the bus..

Did this lady accidentally tap her ezlink card to realised that this is not where she wants to alight.. and stay on to her seat.. till the next two bus stop away.. But old lady thought she was attempt cheating and expect this young lady to give her seat to her.. ???
