Half an hour, come on! :-) We need volunteers every monday, for when we deep clean Pizza Lab together. Come and help for half or one hour - the more people we are, the shorter it takes for everyone.
This way we abide to the high standards of hygiene demanded by commons sense, our customers and the state :-)
When you are here, please ring the bell on all floors. Since we make loud music while cleaning, it's possible that we don't hear you immediately. Make sure to take home a surprise reward!
