It can be fun if you can sneak in some winks at your fellow diners and the waitstaff. Had a delightful company Christmas dinner once with the receptionist's boor of a husband who would do things like stick his dirty finger in the communal sauce bottle and then lick it in front of everyone.  We can't take my in-laws anywhere nice because my planetary MIL has no concept of what's appropriate in public. We once went to a Chinese restaurant, she ordered herself prune juice. When she tried it, she started loudly screaming "Ew!!!! EWWWW!" and pushed it away from herself. Thankfully, the restaurant was almost empty as it was around 3 pm on a weekend, but that sealed the deal for us that we can't take her anywhere where a full meal costs more than $30.
