To find the percentage of customers who had waiting times exceeding 6 minutes, we need to look at the point where the ogive line intersects with the vertical line of 6 minutes and then subtract that value from 100% (total percentage). 
Looking at the graph, we see that the ogive intersects with the 6-minute vertical line at around 89%. 
Therefore, the percentage of customers who had waiting times exceeding 6 minutes is 100% - 89% = 11%. 
So, the correct answer is option C) 11%.
