Whether it's a restaurant or coffee shop, suggested tipping amounts have become a source of irritation for many in Canada. If you've been put off by the preset tipping rates just before tapping your credit card, you're not alone. A new survey stated that most Canadians are "irked" by suggested tip prompts when paying online retailers, coffee shops or sit-down restaurants. In May, Research Co., a company that conducts opinion polls, asked 1,000 adults in Canada to share their thoughts on tipping culture. For example, 37 per cent said they tip at bars, 15 per cent said they tip when buying their food to go, 14 per cent tip at restaurants, 12 per cent tip at cafeteria-style restaurants, and 10 per cent tip at fast-food restaurants.
