Golden Rules for Public transport
Basic courtesies are easily forgotten on public transport, particularly if delays are lengthy and space is tight. Do not perpetuate this.
Always offer your seat to those who need it more than you do. If pregnancy or decrepitude are in any doubt, it is best to quietly vacate your seat, move away and hope that your intended recipient will gravitate towards it.
Be tolerant if sudden lurches (a frequent occurence on buses and tubes) propel you into close proximity with other passengers. Apologise if you're the perpetrator, and smile politely if you're the one being crushed.
Remember that proximity heightens tension and amplifies your behaviour, so be considerate if using a mobile phone, eating, drinking, listening to music or carrying outsized luggage.
Keep conversations with travelling companions quiet and discreet - you don't want everyone on the bus to be involuntarily eavesdropping.
If a fellow passenger wrongs you, ignore it and avoid confrontation. Smile and thank others who show forbearance or gestures of goodwill, including the driver and any staff.
