I am guessing it's the new system where FA's can offer miles or sm. Vouchers as an immediate apology for something that happens on board. Did you give her your SM number? Check your account in a few days, I'm sure some small amt will show up.
I hate snorers, and seriously it would drive me nuts, I use my Bose headphones, it seems to help a bit. But, if I'm not able yo sleep, the snorer won't be able to either, I will keep waking him up.
