I was locked out the front door

There was a case that a house close to mine was broken into by someone and something was stolen. Since then, to prevent thiefs my mother would lock the front door from inside so the key can't open the door from the outside everynight before going to sleep. 

One night at about 9:30pm I went out and came back at about 12:00pm. I took out my key and put it in the keyholde but I wasn't able to open the door. I realized that I should have told my mother that I was going out before. My mother must have thought I was in my room and locked the door. At this time my mom was asleep, but I thought that didn't matter. I need to phone my mother to wake her up but my phone died. I had to shout out to my mother. I shouted several times but my mother didn't hear me. I had to find a phone to call my mother so I went into the street. It's not a walk through the park to find a public phone nowadays and what was more is in the early hours of the morning, there were just a few stores opened on street.
I went into a grocery store and asked if they had a phone. The cashier said nothing and just took out a cellphone from drawer and handed it over to me. I was so thankful! My call got through to my mother then I gave the cellphone back and asked how money for the call, the cashier said I don't need worry about money.
