Customers upstairs bathtub was draining slow due to hair in the drain so I ran my cable to remove the hair and also removed hair directly from the drain waste and ran the cable through the overflow and removed here majority from the wayside that the customer know they had a smaller drain hole so that could also make the water seem like it was draining, but the hair was clogged inside of the drain as well. Customer said he will see how it goes and then think about replacing the drain waste. After testing the drain is flowing normally now.
