An Order of Pizza and Japanese Culture

Today is Inventory Day here at J-List, when we have to count the many thousands of excellent products we stock. It's quite a job, with our entire 15-person staff counting all the items throughout the day, so we make it fun by ordering lunch from Pizza Hut, which 99% of Japanese think is Pizza Hat. Anyway, we mis-calculated the number of people who'd be eating and didn't order enough quite pizzas, making me worried that there might not be enough food for everyone. However, I'd forgotten about the Japanese tradition of enryo (en-RYO), a word which means constraint, modesty or to refrain from doing something, and when we opened the pizza boxes and told everyone to dig in, it took five minutes or more for the Japanese staff to start eating. The girls would take one piece and say they were full, and we had to literally put the pizza slices on plates and press them into people's hands to get them to eat. In the end, there was just enough pizza to go around. It's difficult as an American to completely understand a concept like enryo, but part of the reason it was so hard to get everyone to start eating was, no one wanted to be perceived as being first to grab for food, so they stood around saying, "No, after you" to each other. This was probably due to having so many people in the same place at once. If there had been only 2-3 people and a single pizza, they'd have been less self-conscious.

We did not get the Macross Frontier pizza special they're running, because you have to order medium pizzas for that, and we needed larges this time. Are they implying that otaku don't have friends, or what?
