ok-am I being unreasonable?

So, ok:

Today, I was a dumbass & locked my keys in my car at QT while getting gas. I know, I know...but force of habit, whenever I get out of my car, I just hit the lock button & shut it. Keys in hand, or in ignition

So, I call my friend who works at BestBuy & he's like "O ya-gimme 30 minutes, I'll be up there & help you." So, 30 minutes later-no sign of him, I call him back. He's like "O ya ya-got a lil caught up at work, I'll leave here in 5 & should be there in less than 20 mins." This is understandable. I wait 30 more minutes...no sign of him. So I call again... he's like "Ya, gosh I'm sorry, it's CRAZY around here." I'm like "Well, should I just call a service & ask them to come out & pay for it?" He says "No, no, no-I'll be there, just a bit longer"

Ok-TWO F ING HOURS GO BY AND HE FINALLY COMES TO HELP ME!!!!!!!!!!!!
I was pissed, needless to say. I had NO PROBLEM about calling someone, but he made me wait for two hours!!!!!!!!!!!!!!!!

I mean, should I just be calm about this cuz he helped me for free? CUZ I'M NOT!!!!!!!!!!!!!!!!!!!
