This (they?) would have been in a major magazine like Analog or Asimov’s, I think. Though it’s possible I read it in an anthology collection.
The alien planet had humanoid beings that were fur covered and had a highly developed sense of smell.
One nice touch to indicate the future setting is that mohawk hair and rock&roll music was associated with his grandmother’s time.
The aliens were about 100 or 200 years behind us, like mid 20th century. But individuals had no trouble catching up when given access to advanced materials and lab equipment.
One story's plot concerned a substance that the locals would have been able to smell, and humans don’t have scent-proof containers for smuggling, so it had to be a local bringing it.
Another had a human telling his girlfriend troubles to an alien professor who is incognito as an airport worker, and they share drinks made from pharmacy grade methonal and distilled water so it would be safe for both.
A woman figures out that the (alien) hotel staff has been replaced by grad students studying her, by watching a sport on TV (a cooperative thing called bag drag) and noting their lack of interest.
