It depends. Fresh Wendy's fries are about the best, but they're not guaranteed. It also depends on the Wendy's because I'm pretty sure some just reheat old fries.
Burger King is just the worst. The smells wafting from a Burger King restaurant are rife with promises that can never be kept.
No. BK was my first job, and I actually liked it at the time. Better nuggets. Better tacos. Homestyle buns. Better fries... now it's all garbage and I can never get a Whopper actually put together well.
