hello
Hello you interested in the computer?
I am interested in getting repairs done to my phone
ok I do both computer repairs and phone repairs.
Ok, I just need my phone's screen replaced. I have the screen already just can't do it myself. 
ok well I can do that for you for $15
Ok, I can offer you $9
I can take $5 off since you're a new customer, making it cheap at $10
Ok, sounds like a great deal. thank you
I said $10 dollars not $9.  
Yes I realized I entered 9 on accident when you'd said 10 lol, I am sorry
Well if you promise to refer customers to me I will give you the additional $1 off
Ok, I do have a friend that plans to come with me and schedule a repair as well. Again I am sorry about entering the wrong number
not a problem.
