OMG You don't sell tissues?

What's with the shocked look on their face? Geez 

Customer comes into the pharmacy from the waiting room, and askes to purchase tissues and I said no we don't sell tissues. She shakes her head in disgust and a shock: "What you don't sell tissues in a pharmacy? What happens to ppl who needs a tissue??!" 

Me: "Well although we don't sell tissues here, I can provide you with tissues." I proceed to give her a box to help herself. She grabs it. 

Me: I also add in. "There you go. You can also get some tissues from the receptionist back there at the medical centre. There's a whole box of tissues on the counter over there. Saves you the walk" ....... *rolls eyes*

This is as bad as the providing drinking water story. If anything, a pharmacy is only to be selling medicines. But overtime pharmacies have evolved to sell toiletries, hygiene products, perfume and even groceries (bread/milk).....for convenience and diversification/expansion of business reasons. Back in the old days, you won't even find those stuff in a pharmacy. So stop giving me dirties like we're weirdos for not selling tissues. We don't sell or provide drinking water either esp if you're just a patient waiting in the waiting room to see a dr. Either go next door to the kebab shop and buy water or complain to the building management for not providing a water dispenser for patients. Blah whinge whinge whinge.
