"I would like my stake medium seldom, please."
I have a hard time with the word "ineligible" - easy to read and write, but I just cannot say it without stumbling. No particular part of the word is hard either, it just... comes out wrong. I think it may be unusual way you turn it into syllables: in-el-i-gi-ble.
"Rare" can often be substituted by "seldom", but that doesn't work very well in restaurants. I like my steak medium-well anyway.
