I have just remembered how my various managers used to split me up from people I worked with because we used to chat and enjoy our lunch breaks and work times. McDonald's did this to me and Scottish Widows' too. They couldn't deal with people chatting intelligently about anything and laughing about a crossword puzzle we were communally solving in my drawer. I'd totally forgotten that too. Fun times.
It was probably because it disturbed the others and interfered with the work flow, but at age 19/23 that didn't cross our minds.
Does this still happen?
