<human>: I worked in a very busy clothing store at the mall. The influx of customers was in the thousands and the influx of annoying customers was that number minus 1. I'd constantly have to answer questions about coupons, sales, returns etc. and I was at that stage where I knew when it was coming. I'd cut off the person asking the question and blurt out the answer very robotically. Most of the time, I wouldn't even follow up if that was the help they needed.

Fast foward after a year after I had started that job and here I am shopping at a clothing store (which, I haven't stepped into since I started working at mine because all I would buy were my store's clothes) and I meet a fresh out of high school, first fucking job version of me. I about strangled her with the pants I didn't end up buying.

It made me realize that although I've heard this same question and complaint a thousand times, it could very well be that customer's first time and I needed to treat every customer like new. I gotta  better attitude about it all and it actually lead to a better work experience because customers were much more appreciative.

Summarize the given text in a few sentences.
<bot>: Used to be super snotty to customers until I met a super snotty sales person. Changed my attitude and had a better time at work.
