Not possessing it is reasonable, to a small degree. They should have waited. Or if you were unwilling to wait, and needed it right then and there, then they should have gone and got some. Sod what it costs them. Let them go and bugger themselves.
I know too well what its like IQ, I've had a pretty similar problem, when I want solvents usually, and want them NOW.
Worst was when I needed acetone and all that was available was crappy nail varnish remover. That needed first to be dried, then distilled over dessicant, the distillate collected and redistilled to remove, basically, crap. Ethers are another one.
Wanted diethyl ether, or diisopropyl ether before and whilst I can simply place an order with my supplier for either of those solvents easily, I would have to wait for them to be shipped. And I needed the solvents (back at the time, not right now this minute) not in several days, not even shipped express, but THEN AND THERE,, right NOW, with a flask ready to receive the ether and me ready and waiting to perform the reaction I had in mind. So I wasn't about to wait, and had then to go to an auto supplies store and buy as many cans of cold-start fluid as possible, as they are mostly diethyl ether, one brand being diethyl and diisopropyl ether, with some heptane and a trace of high-boiling cylinder head lubricant grease/thick, heavy oil. The one with diisopropyl ether in it also contains alcohol and acetone too, So I had to buy those, drain the cans, and spend quite some time doing a fractional distillation to separate the contents by distillation at their several respective boiling points until I had clean solvent to use, free from other ingredients, and then dry it too.
Its not pricy, and means I can get hold of diethyl ether without having to MAKE it, either by dripping ethanol into hot, concentrated sulfuric acid and distilling off the ether as it forms, or by reacting ethyl iodide (made by refluxing ethanol and powdered iodine and distilling) with an alkoxide, prepared by reacting more of said alcohol as is being turned into the ether in question, with an alkali metal such as metallic potassium or sodium. Expensive, uses precious reagents and generally a nuisance. The latter method is known as a Williamson synthesis. Works well but expensive to do, especially if one needs large volumes, in which case the sulfuric acid dehydration-condensation is more appropriate and far cheaper.
But it needs boiling concentrated sulfuric, which is somewhat nasty stuff.
