Can you please explain to me about tipping. I have no concept of this what so ever, and it's the only thing I'm worried about (health issues aside!!!). Seriously, major stress I'm gonna offend people. Do you tip EVERYONE? How much? If I ask them outright (hello, am I supposed to tip you, I'm British, help me!) will they be offended? Like do you tip anyone who offers you any help? Reception staff??!! Fast food places??!! People who carry something for you?? Do you tip every time you order a drink????!!!!! Is there a dummies guide anywhere? Do I need to tip you for helping me now??!! Why do you tip so much???!!!! Arghhhhhh!!! Does this mean I will always have to carry cash?????!!!! And change?!!!
