The meal time of taxi drivers is not fixed, because the shift time of each area or vehicle is different. Generally, morning drivers will choose to have breakfast nearby after work. Generally, the morning market and breakfast are open at about 5: 00 in the morning, so it can be judged that the average driver will have breakfast at 5-6: 00, because 6-7: 00 is the morning rush hour and there are more taxis.
