One sure winner

I stopped to get gasoline right before entering DC and went inside the small store to buy the paper. There is a line at the counter. A woman is buying lottery tickets with an unmatched frenzy. She has her wallet opened in front of her and the cashier is counting "17, 18, 19,...". He gets to 30 and hands her tickets. She pays and pockets them all.
More than $20 in lottery tickets. At least someone is winning big at this game...
