Short BG - my DH works in inventory and purchasing for a local chain of grocery stores, and as such has lots of contact with receiving and shift supervisors.
At least once a month, he'll have a version of the following conversation:
*phone rings on a Saturday or Sunday*
Random Guy (RG): LordSnowdon, we're out of *insert random ingredient here*!
DH: Are you sure? I know we were supposed to get a shipment in yesterday.
RG: I'm sure! There's none in *place ingredient shouldn't be*!
DH: Have you checked *correct place for ingredient*?
DH: Have you checked *other possible site*?
RG: Well, no.
DH: Why don't you check those places and see if you can find any. If you don't find any there, send me an email, and I'll order more.
RG: So...you think we might have some *ingredient* still?
I know we have some, since we got a shipment yesterday.
RG: Oh. Well, I guess I can look around some more...
I have no idea why these guys cannot think to *look* for something before they call my DH to complain that they don't have any of it! I keep telling him he needs to record himself saying "Please check all the coolers and on the dock" and just play it on repeat when they call. 9 times out of 10, he comes home the next day, and when I ask if they had to order more *whatever*, he says "No, we had it. It was in *correct place*".
