Based on the location information given it'll probably be Incycle Pasadena. If it is, I'd attribute this story to laziness rather than malice on their part. Altho they are friendly, the guys there seem a bit too chilled out sometimes. The San Dimas store is the Incycle location I tend to go to now, even though I pass both every time I go to work.
Incycle is several blocks off Colorado and OP said just off Colorado. The LBS I think the OP is writing about is on the east side of town and is just a couple or three doors off Colorado. I think the OP did not name the shop for a reason. It was the OP's issue with the shop not ours, so I think it's up to the OP whether or not to name the shop. The shop I'm thinking of is also big enough and disorganized enough that the brifter set could be split up and in different cases thirty feet apart.
