Back in the days of those "brick" phones, the funniest thing I ever saw was one of the Dads turning up at my DD's primary school to collect his son, striding through the playground pretending to be on his phone having a Very Important Conversation, when it suddenly started ringing! All us mums absolutely fell about laughing and he exited with a very red face

Back in the 80s, a work colleague - permanently well-pleased with himself - was the first in the office to get one of these brick-phones. It made him feel Very Important.
He was an industrial surveyor, out in the field on a daily basis, so it did in fact make sense for him to have one. However, he often used it in the office instead of picking up the landline phone. He'd pack up his briefcase with its many zips and locks, stowing the brick-phone at the bottom because of its weight and size, and depart shouting that if we needed him, we could 'catch' him on his "cell".
We regularly waited until he was halfway down the stairs (no lifts in the building) and give him a call, then sneak out on the landing to watch him sit down on the stairs, unzip and unlock his zips and locks, bring out his Motorola brick - and then cut him off... he fell for it every time because of course, it could have been a client calling.
We found out later that in fact very few clients actually called him on his cell - the functionality was poor and its range limited. But, for a while, it made him feel Very Important.
