Additional ‘I want to rip my hair out’ moment

I was asked to pick up 2 lbs of tomatoes for an office lunch time salad on my way back from my break yesterday.  The mere fact that I’m asked to run errands during my break frustrates me to no end, but it was nice out, it takes half a second, and the salad is pretty good, so no big deal.  Except when, upon providing my boss with his change from the purchase, he was amazed that 2 lbs of tomatoes could be so cheap (fyi: I went to Discount Food Outlet).  So amazed in fact, he feigned disbelief.  This is what ensued.  

Him:  This is what is leftover?  Did you get the ones on the vine?

Me: Yes.  I got two pounds.

Him: How big are they?

Me: About.  (I gestured the approximate size.)  I had the cashier weigh them.  It came out to 2.03 pounds.  

Him: You didn’t get the big ones?  I was going to share with everyone. (He starts walking towards the kitchenette to check)

Me:  It’s two pounds of tomatoes.  

(heavy emphasis on two pounds.  no response.  awkward silence)

Him, picking up the bag: Oh, that’s enough.  

No effing way!  To top it all off, I wasn’t offered any salad and I didn’t receive a ‘thank you.’
