What do you think about the spate of photos on social media this year, showing young people engaged in various pranks, especially in restaurants and convenience stores?

Some of them are funny and some a bit irresponsible but on the whole not my business. I can see that if they are damaging to a business then it is a problem but potential employers checking social network sites is often too intrusive into people's privacy. Some people should get a sense of humour or if they can't they should at least give other people a right to theirs.

pranks are fine but not where they are illegal or harm the health, safety, welfare of other.

Pointless. i don't get taking pictures of every banal event or prank and posting on social media.....

They are probably harmless in most cases, how I do think they erode the public's trust in that company. I'm pretty sure that guy at that Takaido Pizza Hut threw away the dough after putting it on his face. But what if he didn't and someone ended up eating it? If that happened (and I'm only saying if), I would think before buying from that shop. And I actually do live very close to that Pizza Hut shop and have bought from there many, many times.

All these pranks should be kept strictly in-house, because they can affect their business if they get into the public domain.

Monkey see, monkey do.
