I'm taking it seriously? All I saw was the prospective VP candidate minding his own business. However, these sentences, as well as the earlier "bad optics" comment, suggest that the poster thinks Mr. Pence's dining reflected poorly on the Trump image:
Pence committed one of the more egregious tourist blunders
Would have been cool for Pence and his family to have been seen there.
Humor is the best way to counter these attacks. Something that Romney and McPain could have used to their advantage in previous elections but they were stiff as cardboard. People just didn't warm up to them.
Trump is a master at dishing it right back with some wit. Hopefully we will see the same from Pence.
