Ten Minutes Supper

We usually have a regular meeting of English circle on Tuesday from 8 pm to 9 pm. I finish working in 7 pm and I need to move, so usually I have no time to eat supper before the meeting. But today I had some time to eat supper, the time was limited though. It was only ten nminutes. But ten minutes was enough for me to finish having supper, so I felt strange when one of our members said it's very short.

Ten minutes supper, is it strange?
