Thank you for the link, sjd guy. Yeah, I had never asked for special treatment in an airport line but that feeling of struggling to breathe had me feeling desperate to not extend what had already been a difficult day of travel.
I suppose I could contact the airport, but you're probably right. They were so callous in person, they won 't care about my email. Perhaps they'll just get a good laugh out of it. It seems that is the kind of people they are. Best to avoid cabo. There are other ways for us to get to the boat.
