Tipping ("dricks") is commonly not expected, but is practiced to reward high quality service or as a kind gesture. Tipping is most often done by leaving small change on the table or rounding up the bill. This is mostly done at restaurants (less often if payment is made at the desk) and in taxis (some taxis are very expensive as there is no fixed tariff, so they might not be tipped). Less often hairdressers are tipped. Tips are taxed in Sweden, but cash tips are not often declared to the tax authority. Cards are heavily used in Sweden as of the 2010s, and tips paid by cards in restaurants are regularly checked by the tax authority.
