Restaurants
You can attract the attention of waiting staff by making eye contact or simply saying ‘excuse me Sir/Madam.’ Waving, calling the names of staff out or clicking your fingers is considered impolite.
Usually, the person who has invited the guests to the restaurant will be expected to pay the bill, although this can sometimes be decided by social rank/standing.
Expect an addition of between 12 -15% on your restaurant bill as a service charge will be automatically added. If no service charge has been added it is accepted to leave approximately 10% of the bill as a tip. It should be noted that tipping is not mandatory.
If you buy a drink at a bar there is usually a small plate for loose change that you may or may not decide to leave your bar staff.
