We don't provide a lot of fanciness at Interesting. No lunch. No small food on sticks. But we do have a tea urn and some tea, milk etc. And, in the past, kind sponsors have been kind enough to provide paper cups for us. However, by the end of the day, we always end up with a soggy pile of dirty and decaying paper cups, which is bad for a number of reasons. This year, therefore, could we suggest, if you'd like a cuppa while you're there, you bring your own mug along. Or perhaps a flask and cocktail glasses.
If you don't have a mug you can acquire excellent ones (as above) here.
