Heather cracked the screen of her old mobile phone a few months ago. She could still read the screen and conduct calls and read emails, but as the months have gone by the touch capability is becoming erratic. One weekend she decides it's time to go visit the local big box electronics store to be able to see the variety of new phones available. She hasn’t looked for a new phone for four or five years, so she wants to get a good feel for the options, sizes, and prices available now. When heather is in the electronics store karina, the salesperson, asks heather if she can help her. Noticing that heather is looking at the mobile phone aisle, what should karina’s next step be?.
