Note! This review is not about the COOP store directly, it is their parking garage which is…read moreattached to side of building. We parked our car there for 3 hours, came back and didn't have enough coins to validate our parking ticket. Machine said we could use coins or notes. Notes needed to be 10 or 20 franc bills. So....we walked around looking for an ATM that allows 20 franc min to be released. Went back to machine and guess what would not except the 20 franc bill. Tried 3 machines on 3 levels with same result. Tried putting the bill in every way possible, even crinckled it up in the end to see if that would help...nope. so we had to find a place in the evening that we could get coins from, not easy in Davos after 7 pm on a Saturday. We are an hour plus into it at this point. By time we got back we owed even more! And although the coins worked be warned it has to be EXACT otherwise it won't accept the final coin. And here is the kicker. None of the machines have credit card as an option. Nearly every other place in Davos has machines that accept credit cards. Anyway wanted others to be warned because the whole experience was so frustrating for us.
