shop (....) 3.6 Editing. Correct the other ten mistakes in the use of modals in this text. I was outside the supermarket when a security guard stopped an old woman as she was have leaving. He said she'd had to come back inside because there was something in her bag that she hadn't paid for. The woman said she can't believe it when the guard asked her to open her bag. She tried to walk away, but the guard grabbed her arm and said she wouldn't allowed to leave until he had checked her bag. The woman got very upset and said he shouldn't grabbed her arm. Then the guard took her bag and opened it. He pulled out a set of pens in a plastic case. The woman was surprised and said it wasn't hers. The guard said she should have been paid for it and he would have call the police now. He pointed to a sign that said 'Shoplifters will prosecuted. Just then a younger woman with a small boy came out of the supermarket and saw what was happening. She said she was sorry because her son may cause the problem. She said he sometimes takes things from the shelf and puts them in her bag. The women's bags were very similar so she thought it must been her son who put the pens in the older woman's bag. The guard said he will have to talk to the manager. I believed the young woman's story because the old woman didn't look like someone who would stolen anything.
