There’s a simple solution to dine-and-dashers and I was happy to deal with it as a customer when one of my favourite eating places implemented it: Have the customer pay up front before the food arrives.
Heck, they may have implemented that for my group specifically because we clearly had a few drinks in us and we might have looked like the sort of group who’d try it. The meaning was clear, but we weren’t bothered. We paid. We ate. We thanked. We left. In that order. Perfect.
Of course, it would turn a tipping system like the US one on its head because the service charge would have to be baked in to the price, but anyone unhappy with service could be given something back after the meal. That is, once the customer’s story of woe has been confirmed, and how much food they ate has been noted.
(If the manager still comps the meal and punishes the server, that’s a different problem entirely. Let’s face it, a terrible manager would have done that anyway.)
To me it seems about as likely an Iranian would spy for Israel as an Afghan would, i.e. not very likely at all. They’d be highly atypical compared to the majority of people in their home country, that’s for sure.
