Starbucks asks customers not to bring guns into outlets

The coffee chain Starbucks has asked its customers in the US to stop bringing guns into its outlets.

Starbucks has not imposed an outright ban, but says guns "should not be part of the Starbucks experience".

The firm has recently become a focus for the pro- and anti-gun lobby, with supporters of the right to carry arms holding a Starbucks Appreciation Day.

In this YouTube video, Terry Holcomb Senior, a supporter of the Second Amendment, is seen walking into Starbucks, in Huntsville Texas with a rifle, after talking to US police officers outside.
