The actual wash at these places are good, but my god are the staff useless.
I had purchased one of the unlimited wash plans online, and went to the Tempe location to redeem it. Which was apparently unheard of / never been done before and overall a shock to everyone there.
What followed was 45 mins of surrealness, 4 different members of staff all trying the same sequence of jabs on the display you drive upto in an attempt to redeem the voucher I brought. None of them actually said words, it was all gesturing and grunts. At several points the arm to go through came up because the attendant had a pass on him, on the 3rd or 4th time I was expected to know that I was to go through for a wash, again with no words...
They eventually gave me a tag, which was useless because it wasn't linked to my account. My first attempt at another location was another 20 mins for them to link the tag to my account for it to be useful.
Please stay away if you expect to interact with the staff.
