The Brits can afford to hold off a bit on Article 50. Right now the EU wants to punish them and make it a nasty acrimonious divorce.
Meanwhile, a number of other countries are planning referendums.
By the time Article 50 is invoked by Britain, the EU just might be negotiating from a position of weakness and fighting other sovereign states on a number of fronts.
If a few others go along with Britain, it might well be the end of the EU.
And really, who needs to be told you can only buy two bananas at a time and they have to be straight, not curved, or other such nonsense.
