Here goes with Problem #1:

Delta, please fix the low pressure problem in the Main A DTW SkyClub, specifically but not necessarily limited to the right (handicapped) shower.

The shower line was 2 hours long today (12/22) and you'd shave that time a bunch if people could get the soap off their bodies more quickly. While you're at it, consider adding more showers at DTW if this waiting time issue is consistent.
