Coffee

I just want them to get it right! Lg Coconut ice coffee, cream and sugar. I pull up to the window, get my coffee and take a sip. No coconut...super bummer. I kindly hand the coffee back and say, "I ordered this with coconut, could you put a few splashes in for me?" He takes my coffee and then hands it back after 15 seconds. I pull away and take a sip. Surely it would be right this time. Uhm...No! How can you get this wrong? It's not like I went at 8am and their were 800 other coffee freaks waiting for their coffee's. Am I wrong to expect somewhat exceptional service from a multibillion dollar company? Why should I expect less? Just because someone makes 8 bucks an hour does not give them the right to be incapable of taking an order and getting it right. And if they get it wrong, and are asked to fix it...how come I can't expect that they'll get it right?
