Burger King complaint: Rude employee and bad drink and over charging

at 11:24 I ordered a $3,00 double burger (with coupon) at this store and the met with a very rude person who argued with me over the time, I always ask for no cheese and never had a problem with that but was told it would be $2.00 more if I left off the cheese, I have been eating there for over 5 years with no problem until recently, the drink I ordered was either diet (which I do not drink) or it was just carbonation wo any syrup in it, which I think is the problem this is the second time I have gotten it this way and is undrinkable.I don’t know what has happened to there business but it is almost non-existant, 2-3 months ago it would have been lined up to the street at lunch time but not lately it is almost empty I always order the burger wout cheese and was told it would now be $2.00 more wo cheese, since when? I use to brag about this store but no more and we have eaten in all the BK’s in this town and this one use to be the best not any more. you need a new Mgr. or bring back the old one. I have worked in the food industry most of my working life so I know how things should work I will be looking for another place to eat from now on, sorry
