Well, depending on how it really happened, if she let an 84 year old cut in front of her out of respect, then she should be rewarded. The woman won an awful lot of money and, even if she gives millions to her family members and friends, will certainly have enough left to write another check. The story is a little confusing. Did the winner actually cut in front of Mrs. Crandell or did she step away for a second? I've been in Publix many times when the customer service people are very busy selling tickets and trying to handle their other duties. They go from register to register. Publix is a very large supermarket chain and each store usually has a separate area for the Lottery. Often customers go the the Customer Service Center to conduct other business and then want lottery tickets. If there's a line to buy lottery tickets, they usually do not get back in line.
In any case, since the winner acknowledged the young woman, she is probably planning to give her a "thank you" reward. I hope so. Otherwise, I don't know why she would even mention her.
