Well, the biggest and the first ever to open McD on Bol'shaya Bronnaya is indeed a scary place (in terms of how they prepare food)!
My brother used to work for McD when he was a student. There would be one 'base' where you'd work most of your shifts but from time to time they'd send you over to other locations "to help out". He had the (bad, presumably) luck to have worked on Bol'shaya Bronnaya for a few days. After what he told me I realised that if I really did want a McDonald's I should: a) never go when it's busy; b) avoid big McDs at all costs!
Если жизнь тебя обманет,
Не печалься, не сердись!
В день уныния смирись:
День веселья, верь, настанет.
Сердце будущим живет;
Настоящее уныло:
Все мгновенно, все пройдет;
Что пройдет, то будет мило.
