Gate Gourmet at MAD is an absolute chaos at the moment. They can't deliver on actual contracts... they don't have enough staff - they have lost IB as the main customer... but they managed to get UX. However, UXs contract started already on the 1st of January... so you can imagine, without any expansion (staff is constantly hired, but they also leave constantly), suddenly Gate Gourmet is catering all of IB and all of UX flights out of MAD.
This will go on, getting worse, until finally Do&Co turns on their kitchens;
