Lock Surgeon

Locked desk - no key. Called for estimate. Told 125$ service call fee plus "cost of new keys". David came on time. Less than 5 minutes to pick lock and remove lock. (Charged another 125$). Ten minutes to cut keys and reinstall lock.(Charged another 125$) plus added 5% "shop supplies" and tax. Over 400$ with no warning! He should have told me before starting job. A business has the right to choose their fees, but should inform customer upfront, especially when they are so misleading and unreasonable.
