Who prepared simple meals carrying their items balanced on a bamboo pole?

This sounds like a description of street vendors in many parts of the world, particularly in Southeast Asia and other regions with a strong tradition of street food.

Here's why:

* Bamboo poles: Bamboo poles are a common and practical tool for carrying loads in many cultures.

* Simple meals: Street food vendors often specialize in preparing quick, affordable, and simple meals.

* Balanced on a pole: This method of carrying food allows for the distribution of weight and ensures stability.

It's important to note that this practice is not limited to any one specific group or region. Street food vendors use various methods for carrying their wares, and bamboo poles are just one example.
