He then placed the bottles back in the bag and sealed it with a tape marked with "Transportation Security Administration INSPECTED."
At the register next to mine at the duty-free store, I overhead a supervisor cautioning another customer not to buy the alcohol bottles that he wanted; apparently, those bottles were made of dark colored glass which does not let the scanner analyze the liquid contents. I am not sure, but I think that the supervisor came over after the cashier refused to place those bottles in a tamper-evident bag.
Spectroscopic analysis of samples is much more easily done with contents inside transparent glass containers than with contents inside variations of opaque glass (with some variations being more of a barrier than others). What would the TSA procedure for STEB-placed liquids have been if the duty-free drinks/perfumes/other liquids were in a container that doesn’t work well for spectroscopic analysis?
