staff kitchens
Once upon a time offices often had a canteen, which had relatively professionally cooked food, and professional equipment and ventilation. Now, the fashion is for a staff kitchen with a self-service microwave and maybe a dishwasher, but usually no ventilation/extraction.
The smells that come out of those microwaves...... Enough to turn my stomach.... especially fish and some pre-packed currys.... And people put that stuff in their mouth?
