The Alpha Phi chapter at Washington U - St. Louis has apologized to City Museum. The chapter has also offered to do community service at the museum, or to assist with fundraising. The museum has politely declined the offers, citing the time that would be needed to train volunteers, and suggesting that the chapter might want to do things at the university instead.
