Shell Gas Station

Not sure what happened to my review from earlier today, but here I go again.
Was here to get some fuel this morning. I normally avoid gas stations with the city limits like I avoid the plague. They are always at least 20 cents a gallon more than out in the burbs. But this morning was running late and didn’t notice I was running low, so I made this one exception to get just enough to get back to the burbs after work.
So I head inside to pay the attendant and notice that he is wearing a bright lime green shirt promoting their new discount program with Jewel. Ding! ding! I remember that I just signed up and have some credit for my Jewel purchases. So i hand the attendant/​owner $ 10 and my Jewel discount card, but he stops me midway and states that he cannot give me the discount. What? So i ask why, and he lamely says that the discount is only for credit purchases at the pump. he then proceeds to tell me that he has no scanner at the counter. Wait, which one is it. you cannot give me a discount because I am paying cash, or because you dont have a scanner?
The discount is not that big, only 5 cents per gallon, but it is the principal. I was pretty upset that the owner couldnt come up with a way to satisfy a customer. All the signage states that cash transactions should see the attendant. WTF!
I will definitely be avoiding this Shell from now on. The owner could have come up with a better explanation for not applying the discount, as he has a scanner to scan his merchandise. It just didnt make sense.
Anywho. Next time I will take my business to Mobil, about a block North on Pulaski.
