1 Tipping upon drop-off of your car is totally optional and is not done by the majority of drivers. Tip your valet when your car is returned to you from the parking lot.  A tip of $1 to $5 is the typical range, with $2-3 being most common.
This shows the valet that you appreciate their efforts and they, therefore, will show respect to your car. Valet Parking Tipping is usually around $2 for each time the valet parks or retrieves your car if there is no parking fee. Now, if there is a parking fee that does not mean that the valet should not get a tip. In fact, the higher the parking fee, the bigger the tip the valet should receive. For example, if parking costs $5, the tip to the valet can still be $2. However, if the parking charge is $10, the valet should be tipped $3; if the parking charge is $15, the valet should be tipped $4; and if the parking charge is $20, the valet should be tipped $5.
