The amount of the tip ("bacşiş") and method of calculating it will vary with the venue and can vary from 1–2 RON to 10% of the bill. The tips do not appear on bills and are not taxed. If paying by card, the tip is left in cash alongside the bill. While tipping is not the norm, servers, taxi drivers, hairdressers, hotel maids, parking valets, tour guides, spa therapists et al. are used to receiving tips regularly, and are likely to consider it an expression of appreciation for the quality of the service (or lack of it). If offering a tip, 5–10% of the bill is customary, or small amounts of 5, 10 or 20 RON for services which are not directly billed. For other types of services it depends on circumstances; it will not usually be refused, but will be considered a sign of appreciation. For instance, counter clerks in drugstores or supermarkets are not tipped, but their counterparts in clothing stores can be.
