Every time I walk into a wireless store, I feel like an unescorted, limping, baby antelope wandering into a circle of hungry lions or jackals. I know I'm about to get devoured.
No matter what I do at that store, no matter how innocent (i.e., ask a question, get advice on phones), my next months bill is inevitably knocked up by $10, $20, $30, or my discounts are stripped off, even though I haven't done anything which should have triggered that.
I hate those stores, and the lowlife cheats that 'work' there.
