if you tap a payment card you risk dropping it in a massive crowd of rapidly moving people often near escalators, stairs or other places where you can watch your precious payment card go bye bye forever
NEVER OPEN YOUR WALLET IN A CROWD - you are a fucking amateur mark
in addition there's no better way to freak out your bank then small sterling tfl transactions - it's the first sign your card is not in your possession
bad plan
same deal with your cell
someone knocks in to you
crash goes your cell
it gets stomped on by 3 sets of doc martens in a row
bad plan
a majority of londoners still use oyster because they can buy discounted 7-day, monthly and annual passes
blend in
look like a local
don't draw attention to yourself
when in europe, do what the locals do
locals may use contactless payment or their phones for goo/app pay
but they don't have to worry about not being able to buy dinner that night or not having a phone for a week
USE A FUCKING OYSTER CARD
