Damn I just wanted a cup of coffee

Went in my store to get a cup or coffee and ended up hanging around cos there was an issue. I didn't want to stay that long, just wanted to go in and get coffee and leave. One of our customer's was charged 4 times for one purchase he made at our store using his emerald card. Time to drink my coffee and finish what I was doing. Grr. I hate when things interrupt me. I'm on a mission and don't want to lose my motivation or train of thought.
