A croupier deals cards for a game of Texas hold 'em. A croupier or dealer is someone appointed at a gambling table to assist in the conduct of the game, especially in the distribution of bets and payouts. Croupiers are typically employed by casinos.
Croup is a condition where the trachea (the tube carrying air to the lungs) and the vocal cords are swollen and may have some muscle spasm. It's usually caused by a virus. Croup causes a hoarse, barky cough (like the barking of a seal) and noisy breathing. Fever, runny nose, and a hoarse voice may also be present. If your child's croup was caused by a virus, it may have easily been caught from someone who has a cold or respiratory infection.
