Idiot shopkeepper

My friends and I want to assemble some electronic stuff.  One of them gave me a diagram of his design, and since I was the only one available to go shopping, oh well.

I really don't know anything about resistors and stuff like that.  So at the end of the long shopping day, I was kind of glad I'd been able to pull all of that all by myself.

Now a few days later I have time to sit down and look up in Google to confirm that whatever I bought matches the specifications.  The results?  The resistors are ten times too resistant and the inductors induct only one tenth of what they're supposed to.

I'm especially pissed off with the resistor incident cause when I arrived to this particular store, although it was 15 minutes before closing time, the shopkeepers were already in a mindset to go home, and this happened at a store that several people had recommended me to go to.  I went in, and the clerks bounced me from one counter to another, and finally to the very first one I'd visited.  Then this moron at the very first counter took a quick look at my paper and he said "no have this", "no have that", etc.  "Only have this", then he went to bring me the resistor and then crossed out the item from my list very proud of himself.  Really imbecile.  I bet his momma is also proud of him.
