我的信用卡欠款太多了：我刷爆了这些信用卡，用来支付我的培训费用了。

I have so much credit-card debt; I maxed them out to pay for my training.

其它怪问题还有，信用卡刷爆了，想让大使馆工作人员付账单，还有一位旅行者问道：“能告诉我怎样才能让我淘气的儿子规矩点儿？”

Other requests have included asking for embassy staff to pay a bill when a credit card had "maxed out" and a traveller asking "Can you t ell me how to make my naughty son behave?"
