What is a coat?

:laugh: I don't own a coat (nor even long pants) so I guess this coat trick isn't going to work for me.
But seriously, Mr Chap, I am a little confused. If the count is such that you are going all-in, it must be somewhat positive, or at least heading in the right direction, so what happens after you put your coat on, go all-in and lose that hand because more small cards hit the felt and the dealer pulled a 5 card 20. No doubt you are not walking from this still increasingly positive shoe, so you are standing there, coat and hat on reaching for more money. Seems kind of silly and even less natural looking.
