Maybe my living with a smoking mother has made me insensitive to it? I've passed through Ullmann plenty, and have never encountered what you suggest.
As for the cafeteria in Amado/Sago, I only pass through there, mostly, and I haven't experienced such things, either.

Anyway, what's wrong with the faculty of Mathematics? Aside from it being slowly taken over by the faculty of Architecture?

Hmm.. well, I'll surely welcome you there, though do realize that Computer Science does require some Mathematical maturity, especially in the theoretical aspects. Now, if you're truely uninterested in Mathematics, I'd advise you to go to one of the real Engineering departments, such as Mechanical Engineering, Aerospace Engineering, and so forth. Their syllabi are very Math-light, and application-heavy. Obviously, you'll need some aptitude for Engineering, to get you started.

Legitimate. Math is not for everyone. I don't think it is, in itself, quite for me, as well, though Applied Mathematics might just be right. But that's for time to say.

Do you know how the Infis are, compared to the Hedvas, by the way? I'm taking the latter chain, but wonder about the former one.
