<prompt> Human: I suppose it depends on which gas station you go to, but today I learned about authorization holds.In the case of a credit card, it just shows up as an extra pending transaction. But if you use your debit card, it can tie up your funds and if your balance is low, cause an accidental overdraft.In my case, today I went to a Chevron, and later looked at my account online. I had a pending charge for 126 in addition to the amount I was charged for gas. Alarmed, I called the credit card company and they explained that this was routine, nothing to be worried about, and the charge wouldnt be posted.I found this article talking about this practice.TL;DRIf your balance is low, dont use a debit card to buy gas or you risk an overdraft!Assistant: If your balance is low, dont use a debit card to buy anything or you risk an overdraft!Fixed that for you...Human: Well, yeah, there is that. :But if you buy gas, and then go grocery shopping, and you expect to have 200 in your account still, it would really suck to overdraft because the gas station decided to charge you an extra 126 that you wont get back for a couple of days.Assistant: 126 seems like a mistake to me. Did you spend 126 on gas?Human: I have a small Toyota. Most of the time I spend less than 40 on gas. Them doing such a large authorization seems excessive to me. I imagine if I was near my credit limit, that would cause the card to be declined. Which would suck if I really needed gas.  <response>: The pump doesnt know how big your tank is until its already given you the gas.
