Depending on the type of business, customer service can be a big part of your shopping experience. Whether or not you're actually offered service, if the staff has a way of lurking around you, or if they're overly attentive can weigh on your impression of a store.

I'm likely to skip out on returning to a restaurant if the service was rude, but customer service at stores hasn't kept me away or driven me to revisit. Have you stayed away from a business or become a loyal customer because of the service?
