To determine the average amount of time a customer waits and is served, we need to add the values in the "Wait Time" and "Service Time" columns and divide by the total number of customers.

Total wait time = 177 minutes 20 seconds 
Total service time = 174 minutes

Total time = (177 minutes 20 seconds + 174 minutes) / 10 customers
Total time = 351 minutes 20 seconds / 10 customers
Total time = 35 minutes 8 seconds per customer

Therefore, the average amount of time a customer waits and is served is 16 minutes 20 seconds (35 minutes 8 seconds / 2). The best choice is option B.
