Definition. 1  Lactose intolerance refers to the inability of the body to digest lactose. 2  Lactose is the form of sugar present in milk.

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.
I look at it this way and this is my honest answer. If you want to know how much you should tip, ask the valet how much their base wage is. Remember, when someone hears valet parking is free, about 60 percent of those who use it won't tip. So you want to keep that in mind.
