I'm an internet shopper at a supermarket so most of my contact with customers is either via the phone or on line- occasionally I may have to do 5/10 mins on a till when the need arises. Our cashiers have a list of things that HAS to be said to each customer namely: Greet the customer, apologise if they've been kept waiting,ask if they need any shopping bags, ask if they need help with packing said bags,state amount owed and finish with a closing remark. On the shop floor if the customer needs direction to a particular item: ask customer to follow you, engage in conversation on the way, hand customer item required, ask if one can help with anything else [one wag asked if I could do their ironing for her] close with a goodbye. This may seem a bit extreme but the cashiers have to adhere to it. I suppose it's better then some supermarkets where the cashier barely looks at you and the only comment made is the amount owed. I'm sure any of you who have been to the US knows it is even more extreme. I took a friend back with me when I retired as I wanted to visit friends and family there. She found even ordering a coffee exhausting, ie: on ordering food - the waiter said 'Good Evening my name is Wayne and I'm your friendly server this evening' then every item of food required is given the third degree.
