再来个狠点儿的，看看俺这个曾经的工程师每天都和啥人打交道

上午同事Shane去给一台昂贵的多级液压泵更换密封，当他把泵解体后看着精密复杂的结构心里没底儿，经理叫我去教教他怎么做，俺到现场后，一边安装一边教他怎么干，装到一大半客户给送来coffee，我们喝着coffee休息一下，我说咱们今天很忙我得走了，你把剩下的活干完，all you need to do is: be patient, be careful, be gentle, don't press the O-rings and gasket too hard, and most importantly: make sure that your hands are clean all the time.
同事笑着说：Sounds exactly like doing foreplay, right?
我差点儿把一口咖啡喷他脸上。
