I hear you on the size anomalies, I remember once upon a time I was a size 4 at the GAP. Now I'm size 0, and I haven't lost any weight. Granted I haven't shopped there in years, but that's just an example.

As for that poor customer service you received, I would write to the customer service manager of that store. What ever happened to the adage "Customer is Always Right"? especially from a big chain store, that's a pretty deplorable service you received.

Once, I bought this down jacket at Old Navy. I hung onto it for less than 2 weeks, and found the exact thing on even more of a sale. I tried to get a price match, she (also just-out-of-teens-manager) said no way. I then said, can I return it so I can buy the other one? she said an emphatic NO to that. How were they to prevent me? I couldn't understand her logic at all, and how she didn't want to work with me. I just returned the sorry thing and walked out, I was so mad.
