We weren't discussing preparation times or elaborate procedures, we were discussing convenience, portability and service time, or in other words; overall friendliness, and those factors are what matter in running a fast food restaurant and for your information Mexican fast food preparation takes long time for some items but the service should be quick for the customer for the business to flourish. Most of the cuisines you cited in your defense of Ethiopian cuisine has robust and rich fast food offerings esp. those of Mexico, Italy and China, a point which is lacking in that of Ethiopia and thus poses a challenge to enjoy wide adoption and achieve the status of mass-market fast food category.
