So most Friday night's my sister and BIL and my ex H will come round for a takeaway/tipple.
We usually go to the same place each time because it's nice food, quick delivery etc.
BIL or Ex H answers the door whilst we get the plates. It's always same driver in red cavalier.
Can always hear BIL/exHmaking small talk, weather, busy? Etc
So they haven't been for a few weeks so me and DP decide to order. My DP is a woman.
Food arrives and door opens, she says hello, thankyou, is there drinks? And thanks goodnight.
All silence besides that, I thought it must have been my hearing but when she walks in I said "did he reply to you?"
She says 'no. He ignored me completely. Wouldn't even look at me
So I ran out 
and asked why he felt it acceptable to completely ignore a customer when she was talking to him and to not even say you're welcome when thanked. First he pretended he couldn't hear me then pretended he didn't speak english. I know he does because we've ordered from them for over a year!
He half mumbled 'sorry' (whilst looking through receipts 
and wound the window up and drove off.
This was last night. I was going to call the shop but thought nothing would be done.
But AIBU to he annoyed that he would have a full convo with BIL and DH but wouldnt even look at my girlfriend?
