Do not tell me I'm stupid for purchasing a regular Game Boy Advance instead of the SP. Why yes, I do know that the SP has a backlight. No, it doesn't matter that the regular GBA isn't as bright. Yes, you can play the GBA at night. It's called playing near a lamp, or hell, even buying a light for it off Ebay. No, I don't wan to upgrade it to a DS. Please don't call me stupid for not doing that either.
I went to my local Gamestop (which used to be an Electronics Boutique) to pick up a GBA for my cousins' for Christmas. I've had both the regular GBA and the SP. The regular was more than sufficient for the kids.
I've been buying games at this location for the last 8 years or so. I know the manager and most of the employees. They never give me shit about what I buy. I guess this was a new guy or something, but it still doesn't excuse his behavior.
