George INSISTED Ron must go this time out into muggle London to browse the sweet shops.
George normally did so but this time he thought it would be good for Ron. Ron didn't see why.
He didn't even see the point in making lots of their tricks even look like muggle candy. Wizarding sweets are much better in his opinion.
Although, he was curious to what had driven his favorite headmaster (no offence intended to Headmaster McGonagall) to both set his passwords for his office different kinds of candy and his crazyness for lemon drops. Ron felt as though he had to get lemon drops, whatever they were, in Dumbledore's memory.
Entering the shop Ron saw stacks of clear cases covering the walls, which he could not see due to the fact these cases were filled with candy.
The candy was generally unlabled as most muggles can recognise a jellybean.
For this reason when Ron took his bag he just filled it up with a couple peices of each type of candy.
The unlabelness was not a problem until when he was in the line for checkout and realized he should get several extra lemon drops. He had absolutely no idea or even a clue to what it even was.
He being who he is Ron simply asked a employee of the store what a lemon drop was and what it looked like.
It did not occur to him until afterwards the look he would recieve after asking such a question.
Ron hunched behind a large box of chocolate bars (a candy Ron was familiar with) and apparated to Wizards Wizard Weazes so he could talk to George, then went right back because he was too embarrassed he could not do this on his own.
Nobody made these mistakes. Not George, Ginny, his dad, Harry, Hermione.... Hermione. What would Hermione do? Then, he realized what he should have done in the first place.
