One of the key rules of office life should be: “Always mistrust a free sandwich.” I’ve been in too many meetings in which the laid-on sandwiches at first glance look like something you might actually pay for but are disconcertingly odd on closer inspection.
It could be a small detail that is off-key, such as pesto chicken in pitta. Or something more unsettling: grated cheese in mayonnaise; mini-baguettes stuffed with cold slabs of aubergine. Either way, be careful what you stick in your mouth while others are droning on.
Some people extend the same suspicion to the “praise sandwich”. This is when a manager begins feedback with heavily buttered praise, then slaps on a slice of criticism before ending with another doughy layer of affirmation.
