Lee's Smoking Grill

So this food truck was in the area and the whole experience was kind of unique. The menu they have listed publicly states that they have a kids meal with a choice of a chicken leg, a hot dog and a side for $5. They also have entrees of pulled pork, pulled chicken, smoked sausage (which I am guessing is in sandwich form) and chicken salad. These entrees varied in price from $5-$7. When I had ordered, I had to actually name of the items of which they did not have my first two orders (no kids meal and no smoked sausage). The gal just went on to tell me that they had chicken salad and pulled pork available. It was nice that they allowed me to sample the chicken salad. But then I went for the pulled pork and then they stated that they had nachos. O_o. So I ended up getting the nachos with jalapenos, sour cream, cheese, and the pulled pork. I was charged $10. Mind you, they did not have a menu on the truck and so this was like a makeshift meal. Suggestions: I would think a menu would be nice for price options and food consideration before customers are set on buying something. It would be nice to follow the publicly displayed menu and have most things available and if not, probably a menu outlining what is actually available (this is why a menu is important!)
