I served drinks late in the lounge. How do I get back on schedule to receive my rewards?

You can serve a free drink every 23 hours. So you can be late by one hour, and still be on schedule the next day. If you served an hour to 90 minutes late, just serve as soon as you can the next day, and you'll be back on schedule the following day. If you served more than 90 minutes late, you'll need to skip a day, to get back on schedule.
