Basically, yes. At least you don't have to tip anyone, and people won't be offended or call you names behind your back.
Tour guides? No tipping as long as you have paid for the tour. Taxi drivers? No tipping, although you can round up to the nearest 10 kr if paying in cash. Bartenders? For a simple order, like opening a bootle of beer, pouring a glass of wine or making a "simple" drink, no tip. Although if the bartender is giving you a lot of recommendations or you have a very complicated order, a small tip is not a bad idea. Someone who helps you with your luggage? No tip, although I'm struggling to see where I'd find someone helping me with my luggage that isn't a taxi driver or works at a hotel. Waiters? You can leave a small tip (5-10%) if you want, but there is no need to and you can just pay the amount on the bill.
