Here is is again, the guide to tipping in the US. If you are not receiving an individually-tailored service, do not tip. Never tip based on an after-tax amount. If you receive any portion of your goods or services gratis, tip as though you were charged the full amount. When paying cash, round up to the nearest whole dollar. Never tip before the service has been rendered, and only tip if you are satisfied with it. For restaurant table service, hair stylist, tattooing, or other personal care or beauty services, tip 15% of your before-tax bill total. Adjust 5% up or down in response to perceived service quality. For a buffet restaurant or food delivery, tip 10% of your before-tax bill total. Do not adjust the amount; if the delivered order is incorrect or unforgivably tardy, do not tip. For bartenders, tip at least 10% of your tab before you leave, minimum $1 per drink, even if you are paying by the drink. If service was not courteous and timely, do not tip. Just leave, and do not return. If you'll be getting too drunk to remember the tip at the end of the night, pay it as you go, with each drink. Don't tip in advance; that's for low-tippers who want to look like big shots. Baristas are not bartenders. If you want bar tips, get a liquor license and put booze in the coffee. For restaurant counter service, drive-through, street stand, fair kiosk, or food truck, do not tip. This is the portion relevant to the article. You do not get a tip for a bog-standard service mandated by the employee manual. Operating the point-of-sale terminal and handing me the goods I just paid for is exactly that. No, I will not pay you 20% to hand me a muffin. If an employee suggests or implies that I should do so, I am less likely to return. If that tip suggestion is inappropriately embedded in the point-of-sale process, that's a management problem, and I definitely won't return. For taxi/driver/shuttle service, tip 10% of the fare. Adjust upward for very good service, but do not tip less than 10% unless you are tipping nothing for very poor service. For baggage handling or porter services, tip 1% the cost of your ticket, delivered item cost, or daily room rate, per bag/parcel, minimum $1 each. For hotel concierge, 10% your daily room rate, per service, on checkout. For hotel maid service, tip 1% your daily room rate, per day, minimum $1, attached to a note at the end of each week, or left in the room on checkout. For independent service contractors/small businesses, such as house cleaners or personal trainers, do not tip, but give an appreciation bonus if you wish on your yearly customer anniversary, or slightly in advance of the year-end holidays.
