Continuity mistake: At the end of the opening scene Willie moves one of the cups in front of him to the middle of the table. The shot changes and they are now both in front of him.
Answer: Mr Tanner actually asks Alf, "Why are you carrying our towels through the den?" The streaming subtitles are wrong when it substitutes "damp" for "den" twice. It's possible the error originated from the VHS or DVD, which occurs often.
