Once a man went to a textile shop and asked for a 120cm jersey.
The salesman humbly expressed “sorry sir, we haven’t got it in our stock but we have 100cm ones. I think it will fit for you because it’s very elastic ”.
Then the man replied “oh it’s very elastic no. I should have thought about that. My little son has got a large one which he can’t ware. I’ll go home and try it out”.
