We were on the train to Birmingham International and we got talking to an elderly couple. They claimed that last year you had to pay for a lot of the food and drink samples. Mercifully that wasn't the case today.
Most of the food and drink producers were giving away small free samples. If we bought some of everything we liked, it would cost a fortune and we wouldn't be able to carry it home. We had to be fairly selective but still came away with a heavy load of wine, cider and spirits.
On the food side, the most impressive free sample was something called Chipstix. These were spiral cut potatoes which were deep fried then sprinkled with seasoning. The stall was promoting the franchise rather than trying to sell the food directly to the public. It made good novelty food and would be a fun alternative to chips, possibly as a side-dish in a pub or cafe.
