这是我今天收到的一则笑话
Store Greeter

So after landing my new job as a Walmart greeter, a good find for many retirees, I lasted less than a day.

About two hours into my first day on the job a very loud, unattractive, mean-acting woman walked into the store with her two
kids, yelling obscenities at them all the way through the entrance. I said pleasantly, “Good morning and welcome to Walmart.
Nice children you have there. Are they twins?’

The ugly woman stopped yelling long enough to say, “Hell no, they aren't twins. The oldest one is 9, and the other one is 7.
Why the hell would you think they’re twins? Are you blind, or just stupid?”

So I replied, “I’m neither blind nor stupid, ma’am. I just couldn’t believe someone slept with you twice. Have a good day and
thank you for shopping at Walmart.”

My supervisor said I probably wasn’t cut out for this line of work.

这最后一句没看懂，是说他的上司不会停止他工作？
