Every year when Santa-Cali-Gon Days comes to town, my dad complains about losing his parking space for the week. You can almost set your calendar to it. Since it started yesterday, I'm just going to go ahead and place this here as a reminder.
We went to the carnival last year and it was around supper time and I was starved. I looked around and saw it in the horizon, "Cletus's Varmint Happy Meal". I thought how could I not. So we approached it and saw Cletus. We said "Excuse me Mr Cletus sir, what is in the Varmint happy meal?" To which he obliged "well, it done contains one critter on a stick, one serving of fried corn fritters, one deep fried Twinkie and a mountain dew." I'll take that please, I replied. As he was packing up my meal, I asked how his day was going. He said, "Well I’m as happy as a mule tick on a fat dog. You're my 300th customer of the day for the Varmint Happy Meal." I paid the man and started to walk away.
As I was walking away I noticed my bag felt very light. Light as air to be precise. So I looked in it and it was completely empty. I walked back to Mr. Cletus and explained it to him."What's that now? I done what again? I ain't never done that before. Hold on a minute as I check something". I waited a minute while Cletus shuffled things around in the cooler. He looked busier than a cat trying to bury its stuff on a concrete floor. He came back and said "Well, I'm as confused as a one legged man in butt kickin contest. I purchased the fixins for 500 Varmint happy meals. However, I still have 465 left over critters on a stick, 475 leftover corn fritters, 475 leftover fried Twinkies and 490 leftover mountain Dews.?" I thought for a minute and replied "Hmmm, It seems I was not the only one to walk away with a empty bag today. It appears at minimum at least X amount of customers got an empty bag today and possibly up to Y amount of customers." You know what to do. Help poor Cletus out and figure out X and Y.
When you get them go to certitude and input them as X-Y, leaving no spaces. You may also assume that no mutliples of any items were included in any bags. It was one or none.

You can validate your puzzle solution with certitude.
I tell you what, if Cletus's brains were dynamite, he couldn't even blow his own nose.
