At my workplace, every galley (kitchen, not quite a break room as there is very limited seating) seems to have a table in it where stuff just appears. It seems to be accepted that this is the "I don't want this anymore, please take it" table. My first question is this a common thing? It is not explicitly marked as such, but stuff just appears on it (books and food), and then it disappears soon after (in the case of books it may take time as the books are usually very old).
Is it OK to take 2 cookies when they appear there? 20? 1 per trip? Does it change for fruit? Books?
