My husband received a $100 gift certificate for Son Cubano which had an expiraton date of 8/05. While we were slow to use it, we went to Son Cubano two weeks ago and they rejected it because it was past the expiration date. I spoke with the General Manager Frank Castro and he stated that while there was no question about its authenticity, they couldn't honor it becaue it had expired. This was not a raffle prize or a freebie, our friend gave them $100 cash. How can cash expire?
