It seems to me like it's only going to get worse as more people get chip cards. The cafeteria at the office where I work replaced their card machine earlier this year with a model that accepts EMV cards and since we have a lot of employees that travel internationally a good chunk of the people that work here pay with an EMV card (myself included). The increased card processing time has resulted in a noticeable increase in the wait time at the register, commonly backing up the line by 1-3 people. I recently figured out the terminal also supports NFC payments so now I use my phone with Android Pay (since it only takes 1-2 seconds vs 10-15) but I'm the only one who uses it so far and I'm not sure anyone else knows.
