I am putting together an online shop & asked DP if there was anything he can think of that we need. He said mayonnaise.
We have three lots of open mayonnaise in the fridge (2 x squeezy, 1 x jar [almost empty]) and one unopened in the cupboard (squeezy)
I said he can't have any more mayonnaise till we are down to at least 2 
He said he prefers mayonnaise in a jar, therefore we need more
If we get more mayonnaise, he will open it BEFORE THE OTHERS ARE EMPTY and I may be pushed over the edge.
Who is BU?
