Could you check my writing, please?

I was working in this evening as usual. A man came into the shop. He looked drunken a lot and had scabs on his left forehead. He shouted and spoke alone in the shop as if there was someone standing in front of him. (or as if someone was standing in front of him.) I felt that this was not that good sign. He picked two bottles of beer and brought it on to the counter. (Or How about "He took two bottles of beer on to the counter"?) And then he groped around his pockets and wallet but it seems that he didn't have enought money for them. He put one of the bottles away and said "I don't have money enough. I will just buy one." He groped around his pockets and wallet quite a while and then finally said "the only I have is 1000won! I will pay the rest 300won, okay? I have only 1000won right now!" I scared of him so I said "okay" to let him just go away. He went out the shop holding the bottle of beer and kicked the door of a police office just in front of my shop. He also threw hard the bottle. After a while he came back into the shop. Oh, how horrible I felt! He shouted and had a conversation with someone invisible again. He never seemed to leave the shop. He shouted at me and babbled on just standing in front of the counter so I called the police secretly. The police came and paid the rest money for a bottle of beer instead of the man. I felt thankful so I said thank you.
