I like to read. That is why I accepted the gig to survey retired people using the library in Breda for Inview in 2018. It was fieldwork which had lots of waiting time between surveys. And sometimes I had to ask people their age. Not all people find it an appropriate question to be asked. All the fieldwork I did for Inview I did as a zzp'er (entrepreneur).
Most of the time the employees of the library brought one of their regulars to be surveyed if I didn't spot the person when entering the library. Because this survey took place in the library and most people going to the library have time I could sit down with the people and let them chat a bit with each survey question.
