Slow service

I just went to Jack tyres to buy two front tyres for my car and immediately after paying for it felt like a trap because suddenly nobody would attend to the car and after 30 minutes of waiting I approached one of the guys for assistance. 15 minutes later I got someone to assist after requesting them. After removing the tyres and fitting them, the guy who was supposed to balance was doing a literal slowgo at this time it's 16:18 after paying for the tyres at 14:58.
