Do you tip when you get breakfast vouchers as part of a frequent guest program? I always do, but I've noticed many people don't. I was talking to someone in a Hilton restaurant Monday morning, and he said he didn't because the tip is covered by the voucher. Is that right? My most recent voucher didn't answer that question and I cannot recall looking on others, but I cannot imagine the restaurants order terminal being set up to compensate a team who served a guest with a free breakfast certificate.
