My cousin works on tills in Tesco and he said you have to follow a process to make sure you full fill the 'happy to help'

Greet the person, offer to pack the bags, chat while scanning and a nice parting comment

Technically the till lady could not do that because the shopper was too rude to wait to make a call, if she had taken if thats fine but to make a call just before being served is rude imo
