Phones4U recommendations winding up my brother

Got this text message yesterday from my brother:

I’m in Phones4U. The customer next to me spends 20 a week on Vodafone, so they’ve suggested putting her on a 70 a month tariff and charged her for a shit Nokia. But if her partner also takes out a phone, then they will get the handset free. What a load of shit.

Isn’t that annoying, when you’re in a phone shop and you overhear someone getting what you perceive to be less than stellar advice?

Sometimes I cna’t help it and I will interrupt and actually suggest alternatives 😉 It’s not good though, when you find that you seem to know more than the sales person does.

Have you ever experienced this?
