Using Spanish at Work!

So one day I was working at the good 'ol Payless Foods in Dyersville. It seemed like just another normal day at work. People come in and buy their grocerys and I check them out. Well that day was totally different. A lot of Mexican families come in and get all their basic foods at Payless. When they come in some of them speak spanish while others do not. Well it was around eight o'clock at night when a group of construction workers came in. Some spoke Dutch, German, and two of them spoke Spanish. The two that spoke spanish came through my line. While I was checking out the lady in front of them, i over heard them talking in Spanish. I looked up and saw they were staring at me, and giggling. I went back to my work. They began to talk again, so I paid attention even more. As it turns out they were talking about how tired I looked to them. I found it quite amusing, because I actually understood what they were saying! I looked up that them and smiled. They gave me they look that was like "Oh my goodness could she actually understand what were are saying" kind of look. I was proud that I understood what they were saying, because if I didnt know any spanish I would have automatically thought they were talking bad about me! it was a gooooooood day!
