Does not tipping on the card change that in any way? I genuinely donāt know, Iāve never not done it. I guess it might, because it means the presentment is for the same amount as the authorisation, but still - I thought most restaurants actually ran the auth a second time when entering the final bill amount, thus the issue.
Can anyone confirm that tipping cash prevents this?
My strategy personally is to always make sure I have a high enough balance (or available credit) to cover any authorisations. Frankly, this is a huge benefit of credit cards. Think how quickly you could run up auths in a week (time for auth to generally expire) travelling the US by car (road trip time). Letās say youāre renting a car, you get fuel twice a day, you stay in a hotel once (hostels are uncommon in the US outside of major cities, and you need some country time - but donāt feel like couchsurfing), and you eat out at a restaurant once a day (itās a nice road trip, lol).
That might look something like (numbers pulled out of my hat and vary widely, especially for hotels, many of which donāt authorise anything - generally nicer hotels do, so Iām assuming a fancy hotel):
- Car rental auth - $1000
- Hotel auth - $300
- Fuel auths - $151/day (1x $150 auth, 1x $1 auth, since those are two common values) - 1057, so Iāll call it $1050 (yes I just ignored the $1 auths, these calculations arenāt precise enough for them to be significant).
- Restaurant auths - $15/day - $105, Iāll call it 100.
Thatās a total of $2450, which Iām just going to call Ā£2000 (thankfully the exchange rate is better than that now, but we have to allow for exchange rate fluctuation).
Ā£2000 of authorisations thatāll never be presented is a very reasonable amount, and many people could go way over that.
Personally, this is one reason I generally use credit cards for things that will create these authorisations. I donāt care if Ā£2000 of pre-authorisations are put on a credit card, thatās a small amount compared to most of my credit limits, and Iāll never see or be affected in any way by them.
However, on my Monzo card, itās a bit more⦠eeh.
