Coffeeshop Starbucks from capital of Argentina used Coinhive script to mine Monero on customer's laptops thru Wi-Fi. Customers weren't warned. This is reported byt the CCN.
The head of a technology company from New York, Noah Dinkin, drew attention to the problem. The expert noticed a ten-second delay when connecting to a Starbucks coffee shop in Buenos Aires. It turned out that at this time the network provider used the power of the devices for Monero's mining.
Hi @Starbucks @StarbucksAr did you know that your in-store wifi provider in Buenos Aires forces a 10 second delay when you first connect to the wifi so it can mine bitcoin using a customer's laptop? Feels a little off-brand.. cc @GMFlickinger pic.twitter.com/VkVVdSfUtT

As soon as we were alerted of the situation in this specific store last week, we took swift action to ensure our internet provider resolved the issue and made the changes needed in order to ensure our customers could use Wi-Fi in our store safely.

Motherboard talked to Starbucks' spokesperson regarding the issue.
Last week, we were alerted to the issue and we reached out to our internet service provider—the Wi-Fi is not run by Starbucks, it's not something we own or control. We want to ensure that our customers are able to search the internet over Wi-Fi securely, so we will always work closely with our service provider when something like this comes up.
In next tweets, Dinkin revealed that the code was found in three separate Starbucks locations over multiple days, and that the internet service’s Terms of Service (TOS) didn’t mention the Monero mining code.
