We get free bread for lunch. Cool, but I don't wanna eat bread.
Coffee is free. Cool, but it is bad quality, my el cheapo espresso machine at home is even better. Plus I'll experience a massive down in the evening. Oh hey, not the employer's problem.
I've never seen free soda anywhere, but the thing is: it is just a lot of sugar, with too little water. I won't drink that if I get paid for it.
At least water is free, and that's important in the summer. I'm free to go grab a cup, and the walk is healthy, too.
Then there's these parties 'for team spirit', with all kind of fried food. Cool. Guess who pays for that?
Screw all this. Like you said; "I'd rather get paid a little bit more."
