Shouldn't have done it!
Good job Dirtyhandslopez, some people want to join the scene and sadly don't have the knowledge/experience/friends or do the research about what they are buying. They just trust to buy what they think is being advertised, doesn't make them mugs or idiots. Glad you didn't take the attitude of 'tough s**t', price the mug out of having his dream as some would rather. It's been a pig of a job for you but customer is happy , someone else is staying on the scene and surely you can take great professional and personal pride out of that rather than squeezing a few more quid. Great job.
