How to safely and gracefully rub a stranger's banquet?

In fact, when you want to be safe and elegant, that is, to rub a stranger's banquet, then go directly to the stranger's banquet to find it. Do anything on the table, male or female? You just sit there, don't sit in front and do your homework. They don't know whose friend you are. You just sit there and don't say anything to anyone. Don't care? Then wait for the bride and groom to come, and then you can, for example, pay for the meal, and then you can go, so that's it, or sit at the table and eat. Well, it's ok mainly without references. When the food is almost the same, go to the toilet halfway, that's all, and then you can go. Anyway, this can be sent to many families, and they don't know who it is. Anyway, there is no list on it, and everyone is sitting casually, and no one knows it, so as long as you eat in it, no one knows it, and you run away in the middle of it, which is still very good.
