There are many factors and possibilities.
Traffic and road conditions.
Engine and transmission performance.
If the engine had not been tuned correctly, you would have performance problems leading to higher consumption and excessive fuel being used.
If the transmission or clutch is slipping, same results.
Short dirving distance and time would add to that.
A heavy foot on the accelerator uses more gas.
