I was visiting my SIL recently and while helping clean up after dinner I asked her where she kept her kitchen roll. She looked at me blankly and said 'what?'. I figured she just didn't hear me properly so asked again where the kitchen roll was and was again met with a confused look. I asked if she had any kitchen roll or if she had run out and she really didn't know what I was asking her for. It was only when I started searching and found the roll in the cupboard under the sink that she said 'Ah, you were looking for PAPER TOWEL!'
Now I don't think I'm the unreasonable one here, surely everyone knows that kitchen roll is another name for paper towel?
What do you call it in your house?
