When I worked at Wyeth Pharmaceutical, their cafeteria made 'cottage pie' and it was horrible. The head cook was from the Caribbean. When she put it together, she dumped the carrots, peas and corn in frozen, mashed instant potatoes on top and placed the whole thing in the oven to heat up. When served, the veggies were still in their raw state. You could tell the potatoes were instant. Very little gravy. I had it once and couldn't eat it.
I was surprised because the majority of employees were medical personnel and used to eating in fine upper scale establishments.
