To be on the Safe Side 保证没走错

In a cinema during a performance one of the audience gets up, makes his way along the row of seats and goes out into the foyer（门厅，大厅） . A few minutes later he returns and asks the man sitting at the head of the row:

Excuse me, was it your foot I stepped on when I was going out a moment ago?

Yes, but it doesn't really matter. It didn't hurt at all.

Oh, no, it isn't that. I only want to make sure that this is my row.

在一家电影院里，一名观众在演出期间站了起来，沿着他那排位子走到休息室去了。几分钟后，他回到那排位子并问坐在首位的那位男士道：

对不起，请问我刚才出去的时候是踩着你的脚吗？

是的，不过没什么关系，一点也不疼。

噢，不，我不是这个意思。我只是想确认一下这是不是我的那排位子。
