Tipping in the Netherlands

kisses

I honestly do not understand why so many websites recommend not tipping your tour guide in the Netherlands?

Tour guides work only seasonally and are paid by the job (and salaries are not that great). In the winter they are mostly unemployed as other jobs are hard to come by, and it is hard to make a living off what was earned during the tour season; so next time you take a tour, and you think your tour guide was great – please tip her/him, and it will be greatly appreciated, even more than kissing!
