whenever i turn on my 5:1 speakers i always turn them on, turn the sound fully down, then back to were i would say is comfortable, even though im never change it.

on my work pc's (well tills) wee have a policy to ask the customer if they have reused any bags just before wee press enter to finish the transaction, i almost ALWAYS forget and have to cancel the paying screen, which screws up the recet.
