I got my "persoonlijke uitnodiging voor het Dutch Open 2021" a week ago. As watching people knock little white balls around isn't a pastime I indulge in, I shall give the event a miss.

By the way, tickets have to be booked online, and the personal details provided have to match those in the Dutch CoronaCheck-app (mangling English is a Dutch hobby). Not that it matters, but I of course do not have that app.
