Do You have pets?
Small children?
Obviously you need to store your liquids somewhere away from these. and don't forget that both can be very cunning in getting into places they shouldn't
I keep mine in me drinks cupboard (under lock & key - no ones nicking my 12yr old single malt or my Mrs Lords custard cream)
Thanks guys as ive got young kids and the last thing i would ever want is them getting there little hands on them plus i've just started doing my own mixing and that is the biggest worry
