This is a tactic I see used on the micro level on Shark Tank where usually Mark Cuban will be like "25 second shot clock, you gotta decide right now." Being a Shark Tank and Dragons Den addict (both Canada and UK versions) I can say the greatest difference between the US version and the others is this tactic. I have never seen any of the Canadian or UK investors do anything remotely similar. Usually they are more impressed by companies that take the time to think about the offers. Just an observation.
