When I was working, I had one 20 minute break during an 8 hour shift, during which all purchasing, eating/drinking and walking to/fro canteen had to be accomplished. Usually this left about 5 minutes to actually do any consuming.

I and my colleagues always found it ironic that we were expected to expound the virtues of healthy eating and/or lifestyles to our patients, yet were left high and dry (literally) when it came to nutrition and avoidance of dehydration for ourselves. All this while doing a demanding and physical job!

I remember the availability of food and drink in my previous job roles fondly.
