Simon Pegg is a big Chelsea fan and he decided to sell the ice cream cones at 90% discounted price because of champions league win. But he got just two flavours choco-mix and strawberry. Pegg is selling strawberry ice cream at $1 and Choco-mix at $2.
Because it's a 90% discounted rate, so he is selling just one ice cream to one person.
Jose Mourinho went to the shop and gave the Pegg $2 and without asking Jose the seller gives him the Choco-mix ice cream cone.
Next, Pep Guardiola comes and also gave the Pegg the same amount i.e. $2.
Now Pegg asks Guardiola which flavour cone does he wants.
Why so different behaviours towards Jose and Pep ?
Solution:
Jose gave him 2 $1 note which indicates he needed the choco-mix ice cream cone. If Jose needed the Strawberry cone he must have put just one $1 note. Pep put just 1 $2 note, so the seller can't judge which flavour cone he wants.
