I've spoken at plenty of conferences, and brought my wife along, and have had my share of complications, and my wife has been able to "wing it," as I expect any adult should be able to do.
I'm not saying it's completely absurd that she should have to wing it, but I just don't feel like this is the substance of the issue being presented. His wife is not a helpless child with no money, information or ability to move freely, so I am just not willing to accept that being escorted out (which was stupid in the first place) is tantamount to being abandoned.
