Never chill your glassware, and decline if served a frosted glass. Why? As the beer hits the frosted glass condensation will occur and dilute your beer, while at the same time alter the serving temperature.
Hand washing glasses is recommended as some dishwashers will leave residues on the glass. If you have a new dishwasher with a sanitation cycle, using that with no soap is a great option as well. Allow your glasses to air dry whenever possible. It is not recommended to hand dry because towels can leave lint which will affect head retention.
