Seat Back Catering
I think 'elf & Safety' would have a fit about seat back catering. Slice of pork pie or sandwices sitting in a cardboard box with no cling film, the return catering sometimes sitting there for several hours in variant temperatures!
We did have spares as 'break ins' often happened usually with a note left I remember one saying " a foreign mouse got her first". It really was very unappetising - the crew never ate them!!
