Although I am one of those throw it on the seat and get going people, usually because I have somewhere to get to, I think the true lack of courtesy are the ones who are so impatient and entitled that they think their time is worth more and can't grant somebody the courtesy of allowing them 30 seconds to a couple of minutes to put their stuff in their purse or wallet. Our snowflake children are growing up and the entitlement attitude is becoming pervasive. Move out of the way, here I come and don't make me wait an extra 30 seconds
Yes, I can see being annoyed with somebody who pulls down their visor mirror and starts applying lipstick and getting themselves ready before moving on, but not the minute it takes to allow somebody the privilege of putting their stuff away neatly.
I actually don't like it when a car pulls ahead a length or two up to finish their business. Sorry, if you stop your car in front of mine, there is no way I am going to open my window to transact my business until you pull away. I have no idea if you are putting your cash away or if you are waiting to rob me. I would much rather you just put your stuff away at the ATM instead of getting your stuff, getting your car out of park, inching up, stopping your car again, retrieving your money and receipt off your seat, putting your receipts and cards away and then pulling out. Takes twice as long to do that.
As for filling out envelopes at the ATM - it seems like all of our ATMS have gone to the "Do you need an envelope" question where the machine spits out a single envelope during the transaction for you to fill out. There no longer are stacks of them at the ATMs that you can take a few to store at home to be prepared. So, you put in your pin number, choose deposit, put in how much and then the machine asks if you need an envelope, you push yes, it spits out the envelope, you take it into your car and fill it out as the machine is beeping "do you need more time?" and then you stick it in the deposit slot. This saves the bank money in regulating the one envelope per customer, but it does add a minute or two to the transaction. For those impatient ones, I have been known to get the envelope, cancel the transaction, and move to the back of the line. But most of the time, I take the time to finish my transaction at the machine.
And taking money out of the ATM and then putting it back in? I have done this several times. I have college kids that sometimes (ok, often) need a cash infusion. I have a copy of their atm card. I will take cash out of my account and then take the kids card and put it into their account. I could write a personal check and deposit it, but one of my kid's chosen bank has a policy of imposing a two or three day hold on a personal check. So, while the funds might be available right away, as soon as the ATM is balanced, often times a hold is put on personal check deposits. So we just deal in cash transfers. Nothing nefarious or underhanded.
