You want cook Spean Brout?

I went eat Pho with my aunt today. Ordered the usual spring rolls and a combo beef noodle soup. The waitor asks, "You want cook spean brout?". Hahaha I tried so hard to not laugh. Then my damn aunt across from me kept saying, "Wah?, huh?, what?, cook what?" and the guy kept repeating "spean brout!". It's cooked bean sprouts!
