You may want to reword the question to something along the lines of: "How to talk to my coworker about (this situation) so that he knows his suggestion helped me, in a way that strengthens our rapport as coworkers and lessens the impact of not buying the exact suggestion" — Lichtbringer 1 min ago

+1 for including the employee's POV. I was this kid when I worked fast food and felt all of this. This answer can be handy for any interaction with retail/fast food/customer service positions. Go in happy and understanding and you'll most likely have a good experience. This happened to me after being on hold for an hour (after a month of trying to fix the problem myself). I was pretty upset, but once the rep picked up I tried to keep my frustration out of the conversation and the rep actually thanked me for being so understanding. These jobs suck and being kind goes a long way. — Lux Claridge 1 min ago
