Epic has a slide, so I guess that's got to count for something.
Seriously though, there's a fine line between having fun and frivolously wasting money. UGM walks that line nicely. There are loads of customer-centric events that (to me, at least) never appeared to be gross misuses of money. For customers visiting Verona's campus, Epic follows this principle pretty well.
However, for Epic employees visiting customer sites, fun with customers usually isn't a priority. While visiting Epic staff could suggest going out for a meal during lunch or after work, many Epic customers prefer that visitors' time be devoted more to resolving issues than extra-curricular socializing. Given various legal and ethical issues around vendors paying for clients' meals and vice-versa, the Epic employees that I've dealt with are doing the right thing, even if it's not necessarily following Epic's 8th principle.
Out of 8 principles so far, Epic's actually following 3 ½ of them (and two of those are gimmes).
