Didn’t happen to me but something v similar has happened so I thought I would post about it and see what you lot think.
Larger woman sitting in the aisle (no one sitting on the inside) priority seat at the front of a double decker bus. Woman gets on the front of the bus with her buggy, as she moves past to get to the buggy area her buggy brushes against the woman as she is kind of leaning out. Woman sitting down starts shouting at the woman with the buggy telling her she should have got on the back and that she needs to wait because she’s getting off at the next stop anyway. Woman with buggy carries on and manages to get through and park up her buggy, woman sitting down keeps turning around to look at the mum imo to intimidate her.
Few points:
As far as I’m aware double decker bus drivers don’t let buggy’s on the back because there’s more than enough space to get through via the front (unless you have a twin buggy I assume?)
Woman did not have a large buggy would not have struggled to squeeze through had the lady not been sitting there.
Yes, I know I’m being a shit head mentioning the woman being larger but I feel like it’s relevant because of the way she was leaning out.
IMO woman should have just sat on the inside of the seat, or just moved temporarily. The bus wasn’t busy so that’s not like the only place she could have sat.
I seriously hate travelling on London buses because of situations like this, when my dd was younger I’d actually choose to walk instead of getting the bus with people like this.
