Let's assume the number of miles driven is m.
The total bill consists of two components: the daily charge of $30 and the charge per mile driven of $0.20m.
The equation representing the total bill is 30 + 0.20m = 80.
By subtracting 30 from both sides, we get, 0.20m = 80 - 30 = 50.
Dividing both sides by 0.20, we find, m = 50 / 0.20 = 250.
Thus, the customer drove 250 miles. Answer: \boxed{250}.
