Free tea? Don't mind if I do

While wandering back to the car park from a quick walk around by York Minster my Mum and I were stopped by a lady with a clipboard and talked into doing a tea taste test at York's Central Methodist Church as part of some market research. We sat down at a table with a researcher and got two samples of black tea (with milk and sugar on hand if you wanted it) and asked to say whether we liked them or not, and whether we thought they were the same, similar or different. They were both fairly nice and similar in taste. After answering her questions I was free to go and asked if I could take one of the cups of tea with me (I'd only drunk a small sip, seemed a shame to waste it). The lady seemed a bit bemused but said that would be fine she supposed. Mum also got given two washing powder samples to try (I saw her being given two small packets of white powder, suspicious). Apparently these market research people are there fairly often so if you fancy trying some free stuff then look out for people with clipboards near Whip-Ma-Whop-Ma Gate in York.
