I went to Cherries for lunch today, and ordered a houmous and salad baguette. They cut it in half for me as I was eating in. As I went to pick up the second half of my baguette, I noticed to my horror something that looked very much like tuna (something I didn't like even when I ate meat) on the roll. Turns out it WAS tuna. I went up and showed the girl who had made it, who apologised and refunded the cost of the baguette.
I don't know how it got there, but it's made me really wary of eating there again! I'm sending them a polite letter asking their staff to be more careful with cross-contamination in future. The thought that I could've eaten tuna makes me sick.
