I adore the ‘greatful’ part! Another international cliché about the Dutch is their obsession with cleaning toilets. The amount of advertising poured into products specifically related to keeping your toilet clean is mind-boggling. And then there’s the different kinds of toilets, one of which constantly needs brushing, if you get my drift. This bit of Dunglish is easily blamed on the cleaning staff, who probably don’t speak English and don’t have to. So flush it.
