while I have to admit that muslims have a right not to sell alcohol (maybe sainsbury's should have non purchase of alcohol and tabbacco products lines clearly marked this allowing muslims and underage cashiers to do their job without the inconveniance to customers who have to wait while some one steps in to do it for them) I fell that someone wanting to work in any area of the medicine should be prepared to deal with these topics. STD's and alcohol are big issues no matter what contry you work and live in.
