This happened last night, so pretty close.

Well, since it was late night, there were very few people in our lobby, mostly security and staff, I was the only one waiting for the elevator, then a lady arrives, I'm guessing is around 40-50 years old, and also waits for the elevator. It looks like she went grocery shopping cuz she was hugging the toilet paper packs, holding bags and stuff, so her hands were full. The elevator arrives, we get in, and as a nice person I offer to press her floor, because I saw that she couldn't unless she were to drop everything she was holding. Now, I live on the 12th floor, and our building goes all the way up to 71, which is the penthouse. This is in Hong Kong so like 90% of people in our building is Chinese. She was one too. So then I gestured that I will press her floor for her, she smiles and says something in Chinese, which I'm guessing is her floor. So as non-Chinese speaking person, I'm touching every number, and waiting for her approval, she was smiling all the time, so I didn't really know which she meant, and then I press what floor I think she means, so I pressed 13, then 16, then 18, then 15, and it went on and on and on. As I told you, our building goes up to 71, *AND I PRESSED LIKE 90% OF THE BUTTONS*. Ok, I'm exaggerating a bit, but you get the idea: Moron presses random buttons, trying to guess which is right. But some I actually *accidentally* pressed, because the buttons were so close apart. So then by the time we arrived at my floor, she looked frustrated but still trying to smile, put everything she was holding on the floor and looked at me and pressed 71. Sht. So basically she was gonna stop at every other floor or so, until she gets to her penthouse. Sht. I upset the richest motherf***** in our building.

For those who want to know what building it is for further proof and research, it's the Grand Promenade in Aldrich Bay in SoHo.
<bot>: I wanted to help a lady press her floor, ended up pressing nearly every floor. Building goes up till 71th floor, turns out she lives there at the penthouse.
